"Gentlemen," soothed Gest, as Chichester half rose from his chair. "We're in too serious a jam to indulge in petty quarrels. We've got to decide what to do——"

"I move we call in the police," growled Kroner. "I still can't believe that any human being could induce such a state of catalepsy, or living death, or whatever you want to call it, in other human beings. Not unless he's a wizard or something. Nevertheless, in view of this threat note from Doctor Satan, there may be a definite criminal element here that the cops should know about."

"Let's wait on the police," objected Gest. "We have already done better than that in summoning this Ascott Keane to help us."

"I've just found out something that I think is of vital importance!" he gasped. "Something in the roulette room! I've been in there all night, as you know, looking around to see if I could find poison needles fastened to table or chairs, or anything like that, and quite by chance I noticed something else. The maddest thing! The roulette wheel! It's——"
