First published in 1944, this was the fourth book to feature Jeff and Haila Troy whose exploits were popular with readers and movie goers six decades ago.
Joint pseudonym. Audrey Kelley Roos [1912-1982] & William Roos [1911-1987] were a married couple who wrote about a a married couple; their series detectives were Jeff and Haila Troy, aided by NY Lieutenant George Hankins. Roos also wrote some non-series mysteries.
Photographer Jeff Troy and his wife Haila are visiting Central Park and run into a group of adult enthusiasts for model boats, which they sail in the lake. When one of them is found impossibly murdered (he's sitting on a rocky knoll and no-one approaches him before he's stabbed), the wife of one of the suspects hires Jeff for the princely sum of $1000--well, it's 1944 and that's a lot of money. Jeff doesn't want to investigate, but Haila insists, and they find themselves questioning a lot of different suspects and getting in a lot of trouble. Humorous, light-hearted, sometimes spooky--the Troys cover a lot of ground until they identify the not-at-all lighthearted motive for murder.
This was an enjoyable, quick read. My first experience with this author (actually written by a husband & wife team), apparently I started in the middle of a series so maybe it would rate higher if read in sequence.
One of the better Haila and Jeff Troys with a plot that can be figured out to some degree (though one twist was confusing to me.) Very enjoyable look at NYC in the 1940s war years.
