Stories from Suspense Magazine #4 Winter 1952: “The Third Degree” by Charles Lenart
Lenart captures the patter of the hardboiled style beautifully, but the surprise ending of his yarn was none too surprising. I found only one other story credited to him that appeared in Detective Tales (June 1951). If it’s the same “Lenart” found online, his writing career focused on copywriting, and he died in Chicago in 2010 after a successful career selling copy.
