Lord John and the Private Matter by Diana Gabaldon

This has finally made it to the top of Mountain TBR! A fascinating account of the military and sexual underworld of London during 18th Century, and with focus on Lord John from the Outlander Series, who sets about trying to establish if his cousin will marry Trevelyan, who it seems has a transmitted disease....plus there is the event of a missing soldier who is found murdered...... Can be read as a standalone book from the Outlander Series, which is equally fascinating!
