Roy writes well to intertwine old beliefs, modern warfare, and medieval religious conflict. Arnold is sent to watch a bridge being replaced, becomes involved in an archaeological dig and a string of murders. Jane involves him into research on her new book and DCI Culpeper in the police investigation.
There is a viking style beserker on the loose and there is pairing up but not for Arnold and Jane. If only Jane were an old stone. The ending builds to high drama but leaves you guessing.
