The Man in the Canary Waistcoat. The Sam Plank Mysteries, #2

In this new mystery set in 1825, Constable Sam Plank suspects there may be a link between a suicide, an embezzler, an arsonist and a thief. No corner of Regency London is untouched by these crimes, as he travels from the mansions of St James's back to his own childhood haunts among the dank alleyways of Wapping. As his steadfast wife becomes involved in his investigations, and with a keen young police officer now under his command, Sam finds himself leading them all into a confrontation with some ruthless and brutal adversaries - one of whom he had hoped never to see again.
