The Winter Queen - Boris Akunin, Andrew Bromfield

‘What it means is not for me to judge. But I have a good idea how things happened. Our well-heeled and pampered gilded youth decided to bid the world farewell. But before he died he wanted to give his nerves a bit of a thrill. I read somewhere that it’s called “American roulette”. It was invented in America, in the goldfields. You put a single shot in the cylinder, give it a twirl, and then – bang! If you’re lucky you break the bank, if not, then it’s goodbye and farewell.

Oh, this IS fun. 

It's a little bit like Sherlock (the BBC series, not Conan Doyle's original) but set in Moscow in 1876.
