A Danish visitor to the area goes missing. Then a local farmer digging a drainage ditch finds a skeleton which appears to have been buried in a boat. Is this a Viking burial or a later imitation? Wesley Peterson's boss, Gerry Heffernan, has other crimes to worry about such as the spate of farm robberies which are becoming increasingly violent.
Wesley wonders whether all these things are connected but even he cannot find any sort of plausible connection. It soon becomes clear that the skeleton is a Viking and Wesley's friend Neil, the archaeologist becomes involved in tracking down how the grave came to be where it is.
As ever with this series ancient and modern are skilfully interwoven with some excellent plotting and believable characters. I did not work out what was going on until very close to the end of the story and the last few chapters are a race against time which had me reading faster and faster to find out what happened. This is a well written series with likeable characters and intricate plots and I would recommend it to anyone who likes their crime stories not too violent and with an historical aspect.
