It's not only secrets that are buried by the water... On the tree-lined banks of Surrey's River Wey, a body is dug up by workmen in the middle of an Anglo-Saxon burial site. But this is no Dark Age corpse... One man seems to fit the bill: Ozzy Blanchard, a contractor employed by the same water firm doing the digging who disappeared six months ago. A shard of metal lodged in his neck turns out to be part of an Anglo-Saxon dagger unknown to archaeologists. Who wielded this mystery weapon, and why? The deeper DCI Craig Gillard digs, the more shocking are the truths that will be uncovered.
