He bent forward and attacked the search once more, his body vibrant with fresh interest. Ellery, smiling, joined him. Cronin stared uncomprehendingly at both. “Suppose you let me in on this thing, folks,” he said in an aggrieved voice. The Inspector straightened up. “Ellery’s hit on something that, if it’s true, is a bit of luck for us and reveals still another sidelight on Field’s character. The black-hearted rascal! See here, Tim—if a man’s an inveterate blackmailer and you find continual evidence that he has been practicing handwriting from textbooks on the subject, what conclusion would you draw?” “You mean that he’s a forger, too?” frowned Cronin. “I never suspected that in spite of all these years of hounding him.” “Not merely a forger, Cronin,” laughed Ellery. “I don’t think you will find Monte Field has penned somebody else’s name to a check, or anything of that sort. He was too wily a bird to make such a grievous error. What he probably did do was secure original and incriminating documents referring to a certain individual, make copies of them and sell the _copies_ back to the owner, retaining the originals for further use!” “And in that case, Tim,” added the Inspector portentuously, “if we find this gold mine of papers somewhere about—which I greatly doubt—we’ll also find, as like as not, the original or originals of the papers for which Monte Field was murdered!” The red-haired Assistant District Attorney pulled a long face at his two companions. “Seems like a lot of ‘if’s,’” he said finally, shaking his head. They resumed the search in growing silence. Nothing was concealed in the foyer. After an hour of steady, back-breaking work they were forced reluctantly to that conclusion. Not a square inch was left unexamined. The interior of the lamp and of the bookcase; the slender, thin-topped table; the secretary, inside and outside; the cushions; even the walls were tapped carefully by the Inspector, who by now was aroused to a high pitch of excitement, suppressed but remarkable in his tight lips and color-touched cheeks. They attacked the living-room. Their first port-of-call was the big clothes-closet inside the room directly off the foyer. Again the Inspector and Ellery went through the topcoats, overcoats and capes hanging on the rack. Nothing. On the shelf above were the four hats they had examined on Tuesday morning: the old Panama, the derby and the two fedoras. Still nothing. Cronin bumped down on his knees to peer savagely into the darker recesses of the closet, tapping the wall, searching for signs of tampered woodwork. And still nothing. With the aid of a chair the Inspector poked into the corners of the area above the shelf. He climbed down, shaking his head. “Forget the closet, boys,” he muttered. They descended upon the room proper.
