Dead Treasure

Treasure of the Dead
(Dane Maddock Origins #9)
by David Wood (2016)

Blown far off course in 1715, a treasure-laden Spanish ship sinks. The sailors struggle ashore, only to encounter a horror out of their worst nightmares.

Despite being labelled an ‘Origins’ story, this happens after Bones & Maddock leave the military.

It’s the usual hunt and search for treasure, ending in a stand off with a villain too sinister to believe.
