Pippsy and Jack Standage are private investigators who visit a luxurious Cotswold hotel for a restful break.

Alas it proves to be anything but restful.

Within a couple of days a car with a dead man in the driving seat arrives at the hotel’s front door. Despite some initial reluctance on Jack’s part, the pair become embroiled in a series of occurrences, which include finding a suitcase full of money in the boot of the dead man’s car and a bag of diamonds lying in the bushes.

The investigating police inspector is perhaps not all he seems, and a number of the other guests look suspicious.

There is an attempt on their lives, and some very nasty people kidnap them more than once! Somehow or other they always manage to extricate themselves, but can they find the criminal brain behind it all?
