Let Sleeping Girls Lie is a 1965 spy thriller novel by the British writer Stephen Coulter, published under the pen name James Mayo.
[1] It is the second in a series of five novels by Coulter, featuring the British secret agent Charles Hood.
The series was an attempt to capitalise on the popularity of the James Bond novels and films.
Writer Anthony Boucher's review noted "Let Sleeping Girls Lie has loads of sex, sadism and snobbery, and no sense at all of plot or structure".
[3] The first Hood novel Hammerhead was made into film of the same title in 1968, but the poor reception ended producer Irving Allen's plans to film the sequels and create a rival to the Bond series.
