At first, I thought to adopt the former approach. On a simple level, the Marlowe books are far more decorous than the raunchy crime novels of today. Could I really, in our foul-mouthed age, have Marlowe telling a tough LA cop to “go boil your head”, the kind of euphemistic invective Chandler had to confine himself to, given the conventions of his day? And what about Marlowe’s mild but politically incorrect attitudes to women, black people and, in particular, homosexuals? Surely, an updating was required.
