"I guess there is no doubt about it, Chick." "Well, if we fail to throw them down, Nick, my money shall go on Kilgore from that moment," declared Chick, with a grin. "What have you dug out of that mess of papers, Nick? Have you arrived at any conclusions?" "Rather!" smiled Nick, significantly. "Did you ever know me to study for five hours over anything of this kind without arriving at some conclusion?" "Never!" laughed Chick. "And the best of it is, Nick, your conclusions nearly always prove to be correct. What's the verdict, old man?" Nick glanced at the French clock on the mantel. "Sit down and light up," he replied. "We have half an hour before getting down to work against this push. I will devote it to informing you of the case as it now appears." "Good enough!" exclaimed Chick, drawing up a chair and lighting a cigar. "Let her go, Nick. I am all ears, as the donkey said to the deacon." "To begin with," began Nick, more gravely, "this order sent to Hafferman, for the diamonds which he delivered at Venner's store, is merely a forgery. Neither Venner nor Garside wrote it, that's as plain as the nose on an elephant's face." "Which is plain enough, surely," nodded Chick. "Furthermore," continued Nick, "the forgery was not the work of any clerk employed in either store. I have compared the writing of each and every clerk with that of the forged order, and I will stake my reputation upon my conclusion. The forgery was committed by some outside party." Nick was an expert chirographist. To have deceived him with a disguised handwriting would have been utterly impossible, and none knew it better than Chick, who now nodded approvingly. "Some outside party, eh?" "There is no doubt of it, Chick. And this conclusion at once suggests two very natural questions," Nick went on. "First, was one of the Kilgore gang in Hafferman's store when Venner went there yesterday, and did he overhear enough of what passed between them to enable him to plan the job done this morning?" "Possibly." "In opposition to that theory, however, is the fact that the forged order is written on one of Venner's printed letter sheets." "By a little adroit work, Nick, one of the gang could have obtained a sheet of Venner's office paper." "That is very true," admitted Nick. "But since this is a theory founded only upon conjecture, with no positive evidence to back it up, the stronger probability is rather to the contrary." "Right, Nick, as far as that goes." "I think so." "And what is the second theory suggested?" "That some clerk in one of the stores got wind of Venner's contemplated purchase, and revealed the fact to one of the Kilgore gang, by whom I am confident--bear in mind--that the crime was committed."
