Black Lizard / Vintage Crime #19 for 2026...

"Comeback", Parker #17, Richard Stark (a/k/a Donald Westlake), published in 1997.

From a GoodReads Review:  "...After Butcher’s Moon (1974), which in a way seemed like a series-ending #16 Parker book, bringing together many characters from previous books, with a slam bang finish, Stark stopped writing Parker novels. His buddy Lawrence Block in his introduction tells us that Stark attempted various novels over the years, and they never worked. But get this: After 23 years he got an idea and it gradually came together, resulting in Comeback (1997)—yup, that’s the only acknowledgement that Parker had gone away at all! And he hasn’t aged a bit. And Stark would write seven more Parker books until his death."
