The body under the bridge - Paul McCusker

A former Scotland Yard detective, Father Gilbert knows about death.
But, as priest of a modest Anglican church in in a small Sussex town, he didn't expect it to show up like this - first in a suicide from the church tower, and then in the discovery of a two-hundred-year-old body beneath an ancient bridge.
The deaths are linked. The mummified corpse reignites a centuries-old battle between two local families - the Todds and the aristocratic Hayshams - and the search for a legendary sword and ring that may have diabolical power.
Against his will, Father Gilbert is thrown into a mix of local violence and depravity, and the underlying motives of both the living and the dead.
