Both these novels are being reprinted by Coachwhip, in spiffy new editions with introductions by me.
I have already blogged about "Amen Dell," aka Irving Mendell (ie, "A Mendell"--get it?), here; but there is more to come on his sole known mystery novel, as well as more on Tyline Perry. Stay tuned.
Also, I wanted to note that I am doing some collection down sizing and I direct anyone interested in buying from my collection to check out my eBay page here. You may see something you'd like. This Tramp has seen a lot of interesting things over the years!
