"That's a very interestin' proposition which has already occurred to me," said Kiddie.

"You see," pursued Rube, "Nick ain't a cigarette smoker. He looks on a cigarette as a childish plaything. He smokes strong tobacco, the same as we found in his pipe. Then why did he take the cigarettes an' leave the tobacco?"

"Dunno," said Kiddie, "unless it was with the idea of leavin' a false clue—a blind. If he had taken the tobacco, I, who know his contempt for cigarettes, might the more readily have identified him."

"Thar's a lot in that notion," Rube acknowledged; "but it's just a bit too cute fer a man like Nick. The galoot that would scatter his footprints around an' leave his pipe in the canoe ain't clever enough ter lay a false trail. Seems to me it's more likely Nick didn't see the tobacco. He was hustlin' to get away with the loot."

"Everything else clear?" Kiddie asked.

"Yes," answered Rube. "I've got the whole thing straightened out."

"Good," nodded Kiddie; "then sit down an' give me your theory, from beginnin' to end."

Isa Blagg appeared to consider it preposterous to appeal for an explanation to a mere boy. Nevertheless, when Rube stated his case the sheriff was constrained to agree with it in every particular.
