Susan Gilruth was the pen name used by the English writer Susannah Margaret Godley (1911-1992) for her seven crime and detective novels published between 1951 and 1963. While her 1956 novel A Corpse for Charybdis was adapted for the radio and broadcast on BBC Radio 4 in 1968 and The Snake is Living Yet (1963) was reprinted in a Japanese series alongside titles by Michael Innes and E. C. R. Lorac in the 2000s, her books have become rare collector's items, and her stories gems to be rediscovered by a new readership.
