Proper old-fashioned mystery
Fair clues, a great setting and an ending I did not see coming. Already on book two.
When a lighthouse keeper's account book washes up a hundred years after the keeper drowned, archivist Nell Fenwick expects a curiosity. Instead she finds a list of payments to people who should not exist, and a final entry dated the week after his death.
To learn who kept writing in a dead man's ledger, Nell must go back to Fenwick Light, the island her family left and never talks about.
