The clang of a bell outside threw us all into worse confusion, and a moment later, almost together, a white-coated surgeon and a blue-coated policeman burst into the room. It seemed almost no time, in the swirl of events, before the policeman was joined by a detective assigned by the Central Office to that district.

"Well, doctor," demanded the detective as he entered, "what's the verdict?"

"Arteriosclerosis, I think," replied the young surgeon. "They tell me there was some kind of hypnotic seance going on. One of them named Errol struck at him with a rubber dagger, and—"

"Get out!" scoffed the Central Office man. "Killed by a rubber dagger! Say, what do you think we are? What did you find when you entered, sergeant?"

The policeman handed the detective the rubber dagger which he had picked up, forgotten, on the floor where Errol had dropped it when he came out from the hypnotization.

The detective took it gingerly and suspiciously, with a growl. "I'll have the point of this analyzed. It may be—well—we won't say what may be. But I can tell you what is. You, Doctor Karatoff, or whatever your name is, and you, Mr. Errol, are under arrest. It's a good deal easier to take you now than it will be later. Then if you can get a judge to release you, we'll at least know where you are."

"This is outrageous, preposterous!" stormed Karatoff.

"Can't help it," returned the officer, coolly.

"Why," exclaimed Carita Belleville, excitedly projecting herself before the two prisoners, "it's ridiculous! Even the ambulance surgeon says it was arteriosclerosis, an accident. I—"

"Very well, madam," calmed the sergeant. "So much the better. They'll get out of our hands that much quicker. Just at present it is my duty."
