The Toff Among the Millions — John Creasey

The Honourable Richard Rollison (aka ‘The Toff') is visiting Easton Hall, a pleasant and quiet country house that has been converted to a hotel. It is said to be more suited to the retired looking for rest than excitement. However, on this occasion it does not live up to its reputation. A man is found dead in the swimming pool, and a little later, The Toff's friend Teddy Merchant disappears. It is then left to him to solve what turns out to be a multi-layered mystery.
