First published in 1948, when it was the best-selling mystery of the year in the author's native Australia, Murder in the Telephone Exchange stars feisty young operator Maggie Byrnes. When one of her more unpopular colleagues is murdered - her head bashed in with a 'buttinsky,' a piece of equipment used to listen in on phone calls - Maggie resolves to turn sleuth. Narrated with verve and wit, this is a whodunit in the tradition of Dorothy L. Sayers and Daphne du Maurier, by turns entertaining and suspenseful, and building to a gripping climax.
