The venture seemed irresistible. Obtain a former Atlantic luxury liner due for demolition and adapt it for gentle holiday cruising around the British Isles. Register the venture in France and run luxury gambling rooms on board. Several men become involved in launching this scheme which appears to prosper until one of them is murdered. Crofts displays all his considerable skills here, timetabling and detailing all aspects of this vast enterprize, providing mini travelogues along the way and contriving an almost fool-proof alibi. Having surveyed most of Freeman Wills Crofts' output in recent years, I would argue with nobody who rated this his best book.
