War game

In the rural peace of modern England, a war game recreates the slaughter of the Civil War. However, when the battle ends, a real corpse is left in the Swine Brook, and an aristocratic but impoverished revolutionary claims to have found a cache of 'Cromwell's gold'.

The story unfolds as David Audley is called in, and 17th-century secrets and the deadly game of modern espionage clash in a complex thriller of bluff and counter-bluff.
