"I have," Geoffrey replied. "It is the blue dress and tam-o'-shanter hat which have played so conspicuous a part lately. But what brings them here? Has Mrs. May a companion hidden somewhere, a companion who might be Marion's sister?" "Seems like it," Tchigorsky said with a dry smile. "But I am not going to enlighten you any further on that question at present. Mrs. May and the girl in the blue dress are two separate people, anyway." "You forget that I have seen them together," said Geoffrey. "I had forgotten that. Well, it won't be long now before the identity of the lady in the smart dress and coquettish hat is established. Meanwhile we came here in search of something far more important than a woman's costume. Help me to turn out all those drawers, and be careful to replace everything exactly as you find it. We have a good three hours before us and much depends upon the result of our search. Keep a keen eye open for papers in any language that is unfamiliar to you." For an hour the search proceeded and yet nothing came to light. There were plenty of bills, most of them emanating from West End establishments--accounts for dresses and flowers, boxes for theaters, and the like, but nothing more. Tchigorsky glanced keenly round the room. "I am afraid we shall be compelled to show our hand," he said. "Mrs. May is so clever that I half expected to find private papers in some simple place, while an examination of her safe would disclose nothing. She has not anticipated burglary and what I am looking for is in the safe." "Dare you open it?" Geoffrey asked. "And show my hand, you mean? I fancy so. We are so near success now that it really does not matter. Put the safe on the table," replied Tchigorsky. The heavy iron box slipped as Geoffrey raised it and clanged on the floor. An exclamation of anger and annoyance came from Tchigorsky and an apology from the younger man. They both stood upright for a few minutes listening intently. But the people upstairs were sleeping the sleep of the just. There came no answering sound. "Blessings upon the pure air and the high conscience that hold these people," Tchigorsky muttered more amicably. "It's all right, my young friend. Hoist up the box, and let us see if my little steel jimmy will have any effect. I would rather have had the key. It is never well to betray your plans if you can----" The speaker paused. From outside a little way off there arose a long, shrill scream, the cry of a woman in distress. The sound set Geoffrey's blood leaping; he pushed for the window, but Tchigorsky detained him. "Where are you going?" he asked sternly. "Outside," Geoffrey exclaimed. "A woman is there. She asks for assistance. Can you stand there calmly and see----"
