Miss Seeton in diamonds and furs at the roulette table? Scotland Yard has disguised the genteel spinster as a high roller to get a police sketch of a mysterious crime boss. But she's soon playing a very dangerous game of big money and murder, and it's a sure bet someone--perhaps Miss Seeton herself, --is in mortal danger.
Retired art teacher Miss Seeton steps in where Scotland Yard stumbles. Armed with only her sketch pad and umbrella, she is every inch an eccentric English spinster and at every turn the most lovable and unlikely master of detection.
