By a Hand Unknown

It's 1991 and Ranling Manor, set among the wild and watery Norfolk Broads, has been home to the Gyllam-Spence family for generations. Open to the public and family-run, its valuable art collection is decaying and conservators Hannah and Nathan arrive to restore its most fragile works.

But underneath the apparent gentility, the Gyllam-Spence family is at war with itself. And someone is stealing from the collection, someone all too close to home. When a body turns up floating in the nearby lake, it seems the stakes have risen to a new high. The police might deem it an accident; Nathan doesn't.

As the family closes ranks, Nathan and Hannah bury their differences and join forces to find out who is responsible. But they will have to be both devious and extremely careful…

By a Hand Unknown is the second in the Dechansay Bright Mysteries but is a complete story and can be read in isolation.
