"Stop, sare, stop! I tell you!" whined Tony.
"Go ahead, then, you brute."
"You know Midsheepman Brimmer?"
"I know him," repeated Dave.
"He tell me, sare, about one joke. He geev me bottle of stuff, and he tell me when this midsheepman, or his friend, come in my place I am to put half of stuff in the bottle in one glass of what the midsheepman order. Then I am to follow the midsheepman out, and watch him until he fall. I am also to have bottle of alcohol with me and sprinkle some on the midsheepman when he fall and lie still. Then I am to go away and let the midsheepman be found. It is to be one grand joke on the midsheepman."
"Give me what is left of the bottle of stuff that Midshipman Brimmer gave you to put in the drink," commanded Dave sternly.
Tony's first impulse was to deny that he had the vial with him. But Darrin's grip on the fellow's arm tightened so alarmingly that the Greek thrust his left hand down into a trousers pocket, then produced the vial, which Darrin pocketed.
"So this is Brimmer's work—and Brimmer was at one time Henkel's roommate and crony!" flashed swiftly through Darrin's mind. "Oh, the scoundrel!"
"Some one ees coming, sare," warned Tony. "Let me go, sare."
"Stay where you are, and don't dare make a move to get away," warned Darrin. "It would do you no good, anyway. I know where to find you."
