A historical mystery set in 1890s London, this Tabitha & Wolf mystery follows aristocratic investigators Tabitha and Wolf as they uncover murder, inheritance secrets, and a hidden ledger in the City of London. When renovations begin at a long-closed counting house owned by Sir Samuel Montagu, workmen uncover a concealed panel containing a family heirloom, a secret letter, and part of an old ledger. What they find is more dangerous than anyone anticipated. The letter suggests that a woman erased from family memory once held a lawful claim that could have changed the fortunes of several families. The missing pages of the ledger may reveal who paid to keep that truth buried. Before Sir Samuel can decide what ought to be done, one of the last men able to interpret the accounts is found dead. Now, Tabitha and Wolf must follow a trail through City offices, old records, and respectable households to uncover the missing ledger before it vanishes forever. The secret hidden behind the panel is not merely a scandal from the past.

It is the motive for murder in the present.
