Affair in Tokyo by
John McPartland. It was first published as Fawcett Gold Medal #406 (1954) with the great cover art by Clark Hulings. (I love pulp cover art)

Although I haven't yet read this one, I read McPartland's Tokyo Rose last month and was impressed both by the well-done mystery and the colorful view of Tokyo in early 1952 just before the end of the Allied occupation. McPartland was a skilled writer who died at the age of 47. I'm delighted to see his Tokyo books published and promoted by Black Mask.
