A German businessman is the third to die: murdered in a seaside guesthouse.

A note pinned on his body is addressed to Colonel Otto Skorzeny, Hitler’s favourite commando and once the most dangerous man in Europe. It warns Skorzeny that they are coming for him next.

Lieutenant Albert Ryan is ordered by the Irish Minister for Justice, Charles Haughey, to protect Skorzeny, but Ryan defied his parents and scandalised his home town to join the British Army and fight the Nazi regime. Can Ryan bring himself to protect a man who caused the deaths of thousands: a man who now lives safely in Ireland in the lap of luxury?
