PROLOGUE IT was 2 p.m. on the afternoon of May 7 , 1915 . The _ Lusitania _ had been struck by two torpedoes in succession and was sinking rapidly , while the boats were being launched with all possible speed . The women and children were being lined up awaiting their turn . Some still clung desperately to husbands and fathers ; others clutched their children closely to their breasts . One girl stood alone , slightly apart from the rest . She was quite young , not more than eighteen . She did not seem afraid , and her grave , steadfast eyes looked straight ahead . “ I beg your pardon . ” A man ’s voice beside her made her start and turn . She had noticed the speaker more than once amongst the first-class passengers . There had been a hint of mystery about him which had appealed to her imagination . He spoke to no one . If anyone spoke to him he was quick to rebuff the overture . Also he had a nervous way of looking over his shoulder with a swift , suspicious glance . She noticed now that he was greatly agitated . There were beads of perspiration on his brow . He was evidently in a state of overmastering fear . And yet he did not strike her as the kind of man who would be afraid to meet death ! “ Yes ? ” Her grave eyes met his inquiringly . He stood looking at her with a kind of desperate irresolution . “ It must be ! ” he muttered to himself . “ Yes -- it is the only way . ” Then aloud he said abruptly : “ You are an American ? ” “ Yes . ” “ A patriotic one ? ” The girl flushed . “ I guess you ’ve no right to ask such a thing ! Of course I am ! ” “ Do n’t be offended . You would n’t be if you knew how much there was at stake . But I ’ve got to trust some one -- and it must be a woman . ” “ Why ? ” “ Because of ‘ women and children first . ’” He looked round and lowered his voice . “ I ’m carrying papers -- vitally important papers . They may make all the difference to the Allies in the war . You understand ? These papers have _ got _ to be saved ! They ’ve more chance with you than with me . Will you take them ? ” The girl held out her hand . “ Wait -- I must warn you . There may be a risk -- if I ’ve been followed . I do n’t think I have , but one never knows . If so , there will be danger . Have you the nerve to go through with it ? ” The girl smiled . “ I ’ll go through with it all right . And I ’m real proud to be chosen ! What am I to do with them afterwards ? ” “ Watch the newspapers ! I ’ll advertise in the personal column of the _ Times _ , beginning ‘ Shipmate . ’ At the end of three days if there ’s nothing -- well , you ’ll know I ’m down and out . Then take the packet to the American Embassy , and deliver it into the Ambassador ’s own hands . Is that clear ? ” “ Quite clear . ” “ Then be ready -- I ’m going to say good-bye . ” He took her hand in his . “ Good-bye . Good luck to you , ” he said in a louder tone . Her hand closed on the oilskin packet that had lain in his palm . The _ Lusitania _ settled with a more decided list to starboard . In answer to a quick command , the girl went forward to take her place in the boat . CHAPTER I . THE YOUNG ADVENTURERS , LTD . “ TOMMY , old thing ! ” “ Tuppence , old bean ! ” The two young people greeted each other affectionately , and momentarily blocked the Dover Street Tube exit in doing so . The adjective “ old ” was misleading . Their united ages would certainly not have totalled forty-five . “ Not seen you for simply centuries , ” continued the young man . “ Where are you off to ? Come and chew a bun with me . We ’re getting a bit unpopular here -- blocking the gangway as it were . Let ’s get out of it . ” The girl assenting , they started walking down Dover Street towards Piccadilly . “ Now then , ” said Tommy , “ where shall we go ? ” The very faint anxiety which underlay his tone did not escape the astute ears of Miss Prudence Cowley , known to her intimate friends for some mysterious reason as “ Tuppence . ” She pounced at once . “ Tommy , you ’re stony ! ” “ Not a bit of it , ” declared Tommy unconvincingly . “ Rolling in cash . ” “ You always were a shocking liar , ” said Tuppence severely , “ though you did once persuade Sister Greenbank that the doctor had ordered you beer as a tonic , but forgotten to write it on the chart . Do you remember ? ” Tommy chuckled . “ I should think I did ! Was n’t the old cat in a rage when she found out ? Not that she was a bad sort really , old Mother Greenbank ! Good old hospital -- demobbed like everything else , I suppose ? ” Tuppence sighed . “ Yes . You too ? ” Tommy nodded . “ Two months ago . ” “ Gratuity ? ” hinted Tuppence . “ Spent . ” “ Oh , Tommy ! ” “ No , old thing , not in riotous dissipation . No such luck ! The cost of living -- ordinary plain , or garden living nowadays is , I assure you , if you do not know ---- ” “ My dear child , ” interrupted Tuppence , “ there is nothing I do _ not _ know about the cost of living . Here we are at Lyons ’ , and we will each of us pay for our own . That ’s it ! ” And Tuppence led the way upstairs . The place was full , and they wandered about looking for a table , catching odds and ends of conversation as they did so . “ And -- do you know , she sat down and _ cried _ when I told her she could n’t have the flat after all . ” “ It was simply a _ bargain _ , my dear ! Just like the one Mabel Lewis brought from Paris ---- ” “ Funny scraps one does overhear , ” murmured Tommy . “ I passed two Johnnies in the street to-day talking about some one called Jane Finn . Did you ever hear such a name ? ” But at that moment two elderly ladies rose and collected parcels , and Tuppence deftly ensconced herself in one of the vacant seats . Tommy ordered tea and buns . Tuppence ordered tea and buttered toast . “ And mind the tea comes in separate teapots , ” she added severely . Tommy sat down opposite her . His bared head revealed a shock of exquisitely slicked-back red hair . His face was pleasantly ugly -- nondescript , yet unmistakably the face of a gentleman and a sportsman . His brown suit was well cut , but perilously near the end of its tether . They were an essentially modern-looking couple as they sat there . Tuppence had no claim to beauty , but there was character and charm in the elfin lines of her little face , with its determined chin and large , wide-apart grey eyes that looked mistily out from under straight , black brows . She wore a small bright green toque over her black bobbed hair , and her extremely short and rather shabby skirt revealed a pair of uncommonly dainty ankles . Her appearance presented a valiant attempt at smartness . The tea came at last , and Tuppence , rousing herself from a fit of meditation , poured it out . “ Now then , ” said Tommy , taking a large bite of bun , “ let ’s get up-to-date . Remember , I have n’t seen you since that time in hospital in 1916 . ” “ Very well . ” Tuppence helped herself liberally to buttered toast . “ Abridged biography of Miss Prudence Cowley , fifth daughter of Archdeacon Cowley of Little Missendell , Suffolk . Miss Cowley left the delights ( and drudgeries ) of her home life early in the war and came up to London , where she entered an officers ’ hospital . First month : Washed up six hundred and forty-eight plates every day . Second month : Promoted to drying aforesaid plates . Third month : Promoted to peeling potatoes . Fourth month : Promoted to cutting bread and butter . Fifth month : Promoted one floor up to duties of wardmaid with mop and pail . Sixth month : Promoted to waiting at table . Seventh month : Pleasing appearance and nice manners so striking that am promoted to waiting on the Sisters ! Eighth month : Slight check in career . Sister Bond ate Sister Westhaven ’s egg ! Grand row ! Wardmaid clearly to blame ! Inattention in such important matters can not be too highly censured . Mop and pail again ! How are the mighty fallen ! Ninth month : Promoted to sweeping out wards , where I found a friend of my childhood in Lieutenant Thomas Beresford ( bow , Tommy ! ) , whom I had not seen for five long years . The meeting was affecting ! Tenth month : Reproved by matron for visiting the pictures in company with one of the patients , namely : the aforementioned Lieutenant Thomas Beresford . Eleventh and twelfth months : Parlourmaid duties resumed with entire success . At the end of the year left hospital in a blaze of glory . After that , the talented Miss Cowley drove successively a trade delivery van , a motor-lorry and a general ! The last was the pleasantest . He was quite a young general ! ” “ What blighter was that ? ” inquired Tommy . “ Perfectly sickening the way those brass hats drove from the War Office to the _ Savoy _ , and from the _ Savoy _ to the War Office ! ” “ I ’ve forgotten his name now , ” confessed Tuppence . “ To resume , that was in a way the apex of my career . I next entered a Government office . We had several very enjoyable tea parties . I had intended to become a land girl , a postwoman , and a bus conductress by way of rounding off my career -- but the Armistice intervened ! I clung to the office with the true limpet touch for many long months , but , alas , I was combed out at last . Since then I ’ve been looking for a job . Now then -- your turn . ” “ There ’s not so much promotion in mine , ” said Tommy regretfully , “ and a great deal less variety . I went out to France again , as you know . Then they sent me to Mesopotamia , and I got wounded for the second time , and went into hospital out there . Then I got stuck in Egypt till the Armistice happened , kicked my heels there some time longer , and , as I told you , finally got demobbed . And , for ten long , weary months I ’ve been job hunting ! There are n’t any jobs ! And , if there were , they would n’t give ‘ em to me . What good am I ? What do I know about business ? Nothing . ”
