A Gun of Many Parts — Peter Mulraney

Criminals, Guns, and a Licensed Post Office.
Easy to use and conceal, Glock pistols are the weapon of choice in the Australian criminal underworld, even though possession of a Glock is restricted under Australian law.
When a Glock with multiple serial numbers is discovered in the wreckage of a car after a senseless shooting, Detective Sergeant Stella Bruno investigates and finds herself on the trail of a group of gun smugglers making creative use of a Licensed Post Office.
If you enjoy mystery and intrigue, you'll love A Gun Of Many Parts, the second book in Peter Mulraney's Stella Bruno Investigates series of quick reads.
