Interestingly I haven't read Fallon yet. It is an earlier work and if I had a copy of every book on my shelf right now I might have started in order of publication. But here we are--I am on my way out of town and grabbed Fallon --published in 1963, February, a year before I was born. The cover on this copy is from 1981and is the books 16th printing--have no idea how many printings have been done of this one since. The cover is a gambler at a table with an ace showing and a gun. We shall see...
Can't wait but I am saving it for the plane ride!
The book is available here:
