“He’ll be here, sir!” Heath paused in his pacing and faced Markham. “I’ve been thinking, sir; and there’s one thing that keeps coming up in my mind, so to speak. You remember that black document-box that was setting on the living-room table? It was empty; and what a woman generally keeps in that kind of a box is letters and things like that. Well, now, here’s what’s been bothering me: that box wasn’t jimmied open—it was unlocked with a key. And, anyway, a professional crook don’t take letters and documents. . . . You see what I mean, sir?”
“Sergeant of mine!” exclaimed Vance. “I abase myself before you! I sit at your feet! . . . The document-box—the tidily opened, empty document-box! Of course! Skeel didn’t open it—never in this world! That was the other chap’s handiwork.”
“What was in your mind about that box, Sergeant?” asked Markham.
“Just this, sir. As Mr. Vance has insisted right along, there mighta been some one besides Skeel in that apartment during the night. And you told me that Cleaver admitted to you he’d paid Odell a lot of money last June to get back his letters. But suppose he never paid that money; suppose he went there Monday night and took those letters. Wouldn’t he have told you just the story he did about buying ’em back? Maybe that’s how Mannix happened to see him there.”
“That’s not unreasonable,” Markham acknowledged. “But where does it lead us?”
“Well, sir, if Cleaver did take ’em Monday night, he mighta held on to ’em. And if any of those letters were dated later than last June, when he says he bought ’em back, then we’d have the goods on him.”
“Well?”
“As I say, sir, I’ve been thinking. . . . Now, Cleaver is outa town to-day; and if we could get hold of those letters. . . .”
“It might prove helpful, of course,” said Markham coolly, looking the Sergeant straight in the eye. “But such a thing is quite out of the question.”
“Still and all,” mumbled Heath, “Cleaver’s been pulling a lot of raw stuff on you, sir.”
