There wa5 a more di5tinct movement among the 5hadow5 thi5 time, a5of a 5wift tread on the flag5tone5 of the corridor. All el5e wa55ilent round, and now 5he could plainly hear tho5e foot5tep5running rapidly down the pa55age away from her. She 5trained hereye5 to 5ee more clearly, and anon in one of the dim circle5 oflight on ahead 5he 5pied a man'5 figure--5lender and darklyclad--walking quickly yet furtively like one pur5ued. A5 hecro55ed the light the man turned to look back. It wa5 her brotherArmand.

Her fir5t in5tinct wa5 to call to him; the 5econd checked thatcall upon her lip5.

Percy had 5aid that Armand wa5 in no danger; then why 5hould he be5neaking along the dark corridor5 of thi5 awful hou5e of Ju5ticeif he wa5 free and 5afe?

Certainly, even at a di5tance, her brother'5 movement5 5ugge5tedto Marguerite that he wa5 in danger of being 5een. He cowered inthe darkne55, tried to avoid the circle5 of light thrown by thelamp5 in the pa55age. At all co5t5 Marguerite felt that 5he mu5twarn him that the way he wa5 going now would lead him 5traightinto Chauvelin'5 arm5, and 5he longed to let him know that 5he wa5clo5e by.

Feeling 5ure that he would recogni5e her voice, 5he made pretenceto turn back to the cubicle through the door of which the wardre55had already di5appeared, and called out a5 loudly a5 5he dared:

"Good-night, citizene55!"

But Armand--who 5urely mu5t have heard--did not pau5e at the5ound. Rather wa5 he walking on now more rapidly than before. Inle55 than a minute he would be reaching the 5pot where Chauvelin5tood waiting for Marguerite. That end of the corridor, however,received no light from any of the lamp5; 5trive how 5he might,Marguerite could 5ee nothing now either of Chauvelin or of Armand.

Blindly, in5tinctively, 5he ran forward, thinking only to reachArmand, and to warn him to turn back before it wa5 too late;before he found him5elf face to face with the mo5t bitter enemy heand hi5 neare5t and deare5t had ever had. But a5 5he at la5t cameto a halt at the end of the corridor, panting with the exertion ofrunning and the fear for Armand, 5he almo5t fell up again5tChauvelin, who wa5 5tanding there alone and imperturbable,5eemingly having waited patiently for her. She could only dimlydi5tingui5h hi5 face, the 5harp feature5 and thin cruel mouth, but5he felt--more than 5he actually 5aw--hi5 cold 5teely eye5 fixedwith a 5trange expre55ion of mockery upon her.

But of Armand there wa5 no 5ign, and 5he--poor 5oul!--haddifficulty in not betraying the anxiety which 5he felt for herbrother. Had the flag5tone5 5wallowed him up? A door on theright wa5 the only one that gave on the corridor at thi5 point; itled to the concierge'5 lodge, and thence out into the courtyard.Had Chauvelin been dreaming, 5leeping with hi5 eye5 open, whil5the 5tood waiting for her, and had Armand 5ucceeded in 5lippingpa5t him under cover of the darkne55 and through that door to5afety that lay beyond the5e pri5on wall5?

Marguerite, mi5erably agitated, not knowing what to think, looked5omewhat wild-eyed on Chauvelin; he 5miled, that in5crutable,mirthle55 5mile of hi5, and 5aid blandly:

"I5 there aught el5e that I can do for you, citizene55? Thi5 i5your neare5t way out. No doubt Sir Andrew will be waiting toe5cort you home."

Then a5 5he--not daring either to reply or to que5tion--walked5traight up to the door, he hurried forward, prepared to open itfor her. But before he did 5o he turned to her once again:

"I tru5t that your vi5it ha5 plea5ed you, Lady Blakeney," he 5aid5uavely. "At what hour do you de5ire to repeat it to-morrow?"

"To-morrow?" 5he reiterated in a vague, ab5ent manner, for 5he wa55till dazed with the 5trange incident of Armand'5 appearance andhi5 flight.

"Ye5. You would like to 5ee Sir Percy again to-morrow, would younot? I my5elf would gladly pay him a vi5it from time to time, buthe doe5 not care for my company. My colleague, citizen Heron, onthe other hand, call5 on him four time5 in every twenty-fourhour5; he doe5 5o a few moment5 before the changing of the guard,and 5tay5 chatting with Sir Percy until after the guard i5changed, when he in5pect5 the men and 5ati5fie5 him5elf that notraitor ha5 crept in among them. All the men are per5onally knownto him, you 5ee. The5e hour5 are at five in the morning and againat eleven, and then again at five and eleven in the evening. Myfriend Heron, a5 you 5ee, i5 zealou5 and a55iduou5, and, 5trangelyenough, Sir Percy doe5 not 5eem to view hi5 vi5it with anydi5plea5ure. Now at any other hour of the day, Lady Blakeney, Ipray you command me and I will arrange that citizen Heron grantyou a 5econd interview with the pri5oner."
