"H--m--m. Yes," said Clancy, closely inspecting the window. "Fire-escape here. Yes. So Sullivan got it all doped out, right off the bat, did he? Clever boy, Sullivan, he sure is." Clancy lingered a few minutes more in the kitchen, though Donald Morris could not, at the time, understand the reason for the delay. The detective stood gazing for quite a while at an innocent little sliver of ice which lay in the kitchen sink, apparently oblivious of his surroundings. When he opened the pantry door, and also looked into the refrigerator, it flashed across Donald's mind that he might be hungry and looking for something to eat, for this, in ordinary circumstances, would be the natural inference from his actions, but if that were the case, Clancy made no mention of it, and at last signified that he had finished with the kitchen. There was only one other room in the apartment, a small one near the kitchen door, evidently intended for a maid's room but not used for that purpose, for a long rod, with a number of coat hangers upon it, crossed one side and a large trunk stood against the wall. The trunk was locked and the coat hangers were empty. A small, plain white chiffonier stood in one corner. The drawers were partly open, disclosing a few gloves and other articles of woman's apparel, all plain, old, and worn. Neither here nor in the bathroom, which came next, were there any signs of disturbance. As they stepped again into the hall, they were aware of a loud knocking on the door at the far end. "That's Sullivan and the captain of the precinct, probably," said Clancy. "I'll go," and passing Morris he went quickly down the hall and opened the door. His surmise proved to be correct. Sullivan ushered in Captain Fitzgerald and introduced his friend, Clancy, with evident pride. Clancy took charge of the situation and conducted the captain through the apartment. The inspection finished, they all returned to the living room, where Morris awaited them. "This is just a simple case of robbery, Mr. Morris," said the bluff police captain, deferentially (for who had not heard of the son and heir of the great Morris estate?). "We'll do our best to get hold of the lad as pulled it, but we're kind of up against it, as you can easy see for yourself. Sullivan tells me that the apartment is rented by the two Miss Blakes and that they're both away. So how can we tell what's been taken, if any? Maybe you, being a friend----" "It happens that I have never been in the apartment before," Morris interrupted, hastily, "though I know Miss Mary Blake very well." "And do you know where the two of them has gone then?" inquired the captain. "No," answered Morris, slowly. "No. I'm afraid I can't help you there, either."
