When Frank Bale was a lawyer, he wore Savile Row suits. Now he has holes in his trousers and serves papers for other, successful, lawyers. Life is bleak but he is kept going by a Philip Marlowe obsession and a longing to prove himself. When a student winds up dead, he gets the chance to investigate a real crime, relying on advice found in an old ‘Tradecraft Manual’ and the sayings of his nan. But neither the manual nor his nan nor Marlowe prepare him for handling the slimiest of London’s underbelly, jellyfish, who hit back first with fists, then with golf clubs and finally with guns. Can Frank stay alive long enough to find the killer – and get the girl?
