‘G. Roy McRae’ is believed to be a pseudonym used specifically for the novelisation of Agatha Christie’s The Passing of Mr Quinn (1928). Nothing else is known about this elusive author.

‘This dramatic film thriller is adapted from a novel by Agatha Christie, the world’s greatest woman writer of detective stories. It provides a new and original type of thriller since three persons in the story could be reasonably suspected of a motive which would prompt them to poison the most hateful villain who ever crossed the pages of fiction. Who, then, poisoned the cruel and sinister Professor Appleby? Derek Capel, his neighbour, in love with the Professor’s wife, Eleanor? Vera, the house-parlourmaid, Appleby’s mistress? Or was it Eleanor Appleby herself? This is a story full of dramatic moments and thrilling suspense. It will keep you guessing until the final page.’ From the original 1928 edition
