“Certainly,” Chick agreed. “That’s good judgment. It may be, chief, that the crook has discovered an odorless and very powerful narcotic gas; also various methods by which he can craftily and quickly administer it.”
“Something of that nature, Chick, which also indicates that he is a man of education, with a knowledge of drugs and mechanics,” Carter pointed out. “All this is what leads me to think there may be some connection between these numerous strange robberies and the mysterious killing of Gaston Todd this noon, if an autopsy shows positively that he was murdered.”
“That’s the case you mentioned?”
“Yes. I now will tell you about it.”
The detective proceeded to do so, covering all of the essential points, both during his observations in the Waldmere Chambers and his call upon Frank Paulding.
“By Jove! this case does have a striking likeness to the others,” Chick declared, after listening attentively. “It may be a murder case, as you suspect.”
“The similarity first led me to suspect it.”
“Naturally.”
“There are three other cases, too, about which Gleason told me, that are fully as peculiar,” Carter added, knocking the ashes from his cigar.
“What are they, chief?” questioned Patsy.
