UK Pulp - Michael Barnes!

 Michael Barnes.

 Donald Cresswell was a prolific writer of crime novels under the pen-name Ross Angel in the 1950-54 period, writing primarily for Scion Ltd., who had a top-flight range of gangster writers (Vic Hanson, Dail Ambler, Bevis Winter, Michael Barnes). I'm pretty sure Cresswell, who was writing a book a month for Scion, used other pen-names or had his work tucked away under house names (created by the company and used by a number of different authors). Pierre Cresson was a Cresswell pen-name; he definitely also wrote at least one novel under the Nat Karta house name and I have a notion he may have also written as Hans Vogel and Bram Casson
