Books in the The Three Evangelists series

When two Parisian women are shockingly murdered in their homes, the police suspect young accordionist Clement Vauquer, who was seen outside both of the apartments in question. But what Louis uncovers is anything but straightforward, and he must call on some unconventional friends to help him solve his most complex case yet.

The opera singer Sophia Simeonidis wakes up one morning to discover that a tree has appeared overnight in the garden of her Paris house. Intrigued and unnerved, she turns to her neighbours: Vandoosler, an ex-cop, and three impecunious historians, Mathias, Marc and Lucien - the three evangelists.

Keeping watch under the windows of the Paris flat belonging to a politician's nephew, ex-cop Louis Kehlweiler catches sight of something odd on the pavement. A small white object, surrounded by the excrement of local dogs. A piece of bone. Human bone, in fact.
