I should do a second part then :-)? Was a love drama - duel. Look what Wikipedia said:

"Pushkin was fatally wounded in a duel with his brother-in-law, Georges-Charles de Heeckeren d'Anthès, also known as Dantes-Gekkern, a French officer serving with the Chevalier Guard Regiment who attempted to seduce the poet's wife, Natalia Pushkina."
