When the family butler is brutally attacked, land agent Matthew Rowsley and his wife Harriet determine to find the culprit in this gripping Victorian mystery.

With his lordship's mental health failing, management of his grand country estate has been assigned to a group of trustees, including land agent Matthew Rowsley and his capable wife Harriet. But the smooth running of Thorncroft House is disrupted by a series of unforeseen events. Building work on the estate workers' new cottages is halted by the discovery of Roman remains. Shortly afterwards, the family butler is brutally assaulted and left for dead. A random attack - or was he deliberately targeted?

Matters take an even more disturbing turn when Lord Croft's long-lost cousin and heir, Julius Trescothick, arrives from Australia, ready to claim his inheritance. But is he who he claims to be . and what are his true intentions?

If they are to preserve Thorncroft House and a way of life that has continued for centuries, Matthew and Harriet must uncover the truth behind Trescothick's identity and solve a series of interlocking mysteries.
