Based on the table of contents in the sample, The Complete Jake Samson Mystery Series Vol 1-6 is pretty much what it says it is – all six titles in the 1980s – 1990s series by Shelley Singer. It is free right now at Kindle US and UK. I remember reading and enjoying several of the books in this series many many years ago, in paperback days. I don’t remember much about them, to be sure, but I must have enjoyed them since I kept the original books. The series titles in the omnibus are: Samson’s Deal, Free Draw, Full House, Spit in the Ocean, Suicide King, and Full House. The blurb also indicates that this omnibus includes a bonus dystopian thriller, Torch Song. This omnibus goes free every few months, but never for very long, so grab it now (April 4, 2021) if you want it.
