   But Akunin picks a new genre, for his Seagull is a murder mystery. Treplev does not commit suicide, as he does at the end of Chekhov's play; rather, he is killed, and the remainder of the play consists of a series of tableaux, each featuring a different, plausible murderer. The Hercule Poirot of the play is Doctor Dorn - who himself turns out to be one of the possible murderers. An animal rights activist, he objected to Treplev's habit of shooting things, including a seagull.
