Never before has the queen of spades Laima Skalbe, the leader of the secret group “U,” dealt with such exotic things: a detective with a cat, a dwarf with a bell, black knife throwers and a mulatto killer... And it all started with detective Arseny Kudesnikov. It was he and his cat who discovered an unconscious lady on a deserted highway. The beauty didn't even remember her name. But under the elastic of her stocking, she discovered some kind of address on her leg. The nameless lady was simply eager to find out what happened to her, went to the indicated address and... ended up in the secret apartment of the new chief of the "U" group, Igor Tatarov. He obviously saw this beauty for the first time, but took her to his agent, who said: he had already had the two of them together, and Igor called the lady Emma. Tagirov is perplexed - he doesn’t remember this. And so Igor threw the all-powerful trinity into this matter: Laima, Korneev and Bear, plus Arseny and the cat. This is where the devilry began with the dwarf, the mulatto and the blacks. But no one has ever left the glorious trinity!..
