As passengers board the overnight ferry from the Netherlands to England, a desperate little man frantically pleads for a cabin as if his life depended on it. But the ship is overbooked, and his only choice is to sleep in a lounge with everyone else, including Chief Superintendent of Scotland Yard Henry Tibbett and his wife, Emmy, who are returning from a holiday in Amsterdam.
The next morning, the man is found dead -the victim of a killer who had to be one of the Tibbetts' sleeping companions in the lounge. Furthermore, the dead man turns out to have been carrying a fortune in stolen diamonds, which have disappeared.
This was a fun read, and I'll probably look up more by this author.
