Here’s the newest book from Fayetteville Mafia Press, an indie publisher founded by David Bushman and Scott Ryan and distributed worldwide by Simon + Schuster. This is a fictional murder mystery set in 1970s NY at the film production company run by John Lennon and Yoko Ono and written by Dean Thompson, one of their employees at the time. John and Yoko pop up as characters in the book and are seen through the lens of someone who was interacting with them every day.
