I really thought I had written some more reviewy stuff about some of them but... I think that only happened in my head. However, I did write this post about them, which talks a little more about their... level of interestingness to me vs perceived writing quality:

I was surprised to learn that these stories, written pseudonymously by literary critic and NYC cultural avant-garde elite W.H. Wright, were all bestsellers at the time of publication, but have since faded so far from modern cultural awareness that I'd never heard of them in spite of having been close to several big-time golden age detective fiction fans. (If you read them, you'd probably also begin to feel you understand why they haven't stood the test of time as well as ACD, Christie, and Sayers, but I haven't quite applied myself to articulating my speculation yet.)
