Behemoth

I managed to find one of Mikhail Bulgakov's novels online; The Master and Margarita.

In the story the Devil visits Stalinist Moscow to see if he can do some good.

"Not causing trouble, not touching anything, fixing the primus." — Mikhail Bulgakov (The Master and Margarita)

"'I shall sit down,' replied the cat, sitting down, 'but I shall enter an objection with regard to your last. My speeches in no way resemble verbal muck, as you have been pleased to put it in the presence of a lady, but rather a sequence of tightly packed syllogisms, the merit of which would be appreciated by such connoisseurs as Sextus Empiricus, Martianus Capella, and, for all I know, Aristotle himself.'
'Your king is in check,' said Woland.
'Very well, very well,' responded the cat, and he began studying the chessboard through his opera glasses.
'And so, donna,' Woland addressed Margarita, 'I present to you my retinue. This one who is playing the fool is the cat Behemoth...'" — Mikhail Bulgakov 
(The Master and Margarita)
