My friend Mark Jenkins is an intelligent and usually a very careful man. When he took from "Smiler" Callahan a cigar which had every appearance of being excellent, innocent Havana, the act denoted both intelligence and caution. By very clever work he had traced the poisoning of young Ralph Peeler to Mr. Callahan's door, and he believed this particular cigar to be the mate of one smoked by Peeler just previous to his demise. And if, upon arresting Callahan, he had not confiscated this bit of evidence, it would have doubtless been destroyed by its regrettably unconscientious owner.
But when Jenkins shortly afterward gave me that cigar, as one of his own, he committed one of those almost inconceivable blunders which, I think, are occasionally forced upon clever men to keep them from overweening vanity. Discovering his slight mistake, my detective friend spent the night searching for his unintended victim, myself; and that his search was successful was due to Pietro Marini, a young Italian of Jenkins' acquaintance, whom he met about the hour of 2:00 A.M. returning from a dance.
