'In the disreputable dance-halls and 'houses of accommodation' of 1870s London, a boastful killer selects his prey.

Webb begins to suspect a connection between the terrible murders, a mysterious theft at the Abney Park Cemetery, and a long-forgotten suicide.
His investigations lead him, in turn, to the Holborn General Mourning Warehouse, devoted to the sale of 'Mourning for Families, In Correct Taste,' and its proprietor, one Jasper Woodrow, a seemingly respectable businessman. As Webb delves into Woodrow's life, he uncovers layer upon layer of deceit. But can he unearth Jasper Woodrow's darkest secret, in time to prevent another tragedy?
