Ready for a snowy ride aboard the Train Blanc? Murder and mayhem await. November, 1935. With its velvet sofas and bone china teacups, the Train Blanc is a haven of 1930s luxury. But for Ruby and Fina, the trip holds some shocking surprises - not least that one of their fellow passengers is a murderer … As the famous train steams through the cold Alpine night, the detective pair must work out which of the travellers is not what they seem. Could it be the friendly Swiss priest? The glamorous erotica author? The 'artistic' dilettante? Or even the grandmother with the hideous knitting? Ruby and Fina are at the top of their game in this witty, sophisticated tale, which weaves together politics, fashion, intrigue and romance in a mystery with more twists and turns than a train track through the Alps.
