Garment of Shadows, Laurie King

1924. Mary Russell is missing in Morocco. She wakes up in a small room with blood ingrained in her nails and a memory full of holes. Her skills have not deserted her though, she's in the city of Fez, although she still has no idea how she came to be there.

Fez is home to a rich blend of spies, bandits, diplomats, guides, merchants and some old friends. Lying as it does so close to a bubbling civil war front which many European interests are keen to meddle in, a still-recovering Mary and her husband Sherlock Holmes attempts to piece together her missing hours and the bearing they may have on peace talks in the region.
