David Cleveland - an investigator for the Jockey Club - is sitting in a dinghy in a pleasant little fjord in Norway. He's here to help the Norwegians find out why Bob Sherman, a visiting English rider, has done a runner with the racehorse takings.
He thinks it'll be a straightforward job, and he'll get to spend some time with old friends.
But when the dinghy is hit by a speedboat and Cleveland almost drowns, he realises that there is more to this case than some missing money - especially when a dead body turns up.
Now Cleveland knows the stakes are dangerously high. A sensible man would leave it to the police and go back home to England. Except, it turns out, that England isn't safe either . . .
