Rex Stout, but not Nero Wolfe. Dol (Theodolinda) Bronner, in fact. Also an appearance by Inspector Cramer, just in case you were in any doubt whether it was the same universe. (Wolfe goes back to 1934; publication date, that is.)

More of the rich in and around New York city, and the young people who have no purpose in life, and perhaps some modest talent in something. And another made-up brand-name for guns (Holcomb).

I don't think Stout deals all that well with a detective who can't win a fight with most of her suspects and contacts (not that she loses; she at least avoids fighting). And although her agency appears to have employees and multiple cases in process, she still seems rather new to the business and rather ignorant about a lot of procedural things.

Of course, in 1937 a female detective is fairly radical.

The first murder scene, and Dol's reconstruction of what the process must have been, is really quite chilling.

And, in the end, the strangled pheasants even turned out to be significant. Strangulation was apparently his thing. I guess he killed three people, which almost makes him a serial killer.
