I‘ll admit I issued this book from the library purely based on its title- who doesn‘t want to read a book called “Shark Arm”. It didn‘t disappoint my expectations- literally opening with a captured shark in a Sydney aquarium, vomiting up a severed, tattooed arm. What evolves, is a story of a criminal underworld in 1930s Sydney. There‘s smuggling, gambling, drugs, insurance fraud, violence, you name it, it‘s here.
