The sardine-tin bomb in the father's house
Nikolai Ableukhov, a dissolute student who once rashly promised a revolutionary party a favor, is handed a bomb disguised as a sardine tin with a clockwork timer and ordered, via the provocateur Lippanchenko and the terrorist Dudkin, to kill his father, Senator Apollon Ableukhov. He sets the timer, then loses track of the tin, which the senator carries off to his own study. It explodes without killing anyone, yet it destroys the family anyway: the senator retires, Nikolai goes abroad, and Dudkin, driven mad, kills Lippanchenko.
