Hulbert Footner (1879–1944) was a Canadian writer of non-fiction and detective fiction. About 1920, Footner began to write detective fiction, his first series detective character being Madame Rosika Storey. This is the seventh book of the succesful mystery series Madame Storey, by canadian-american author Hulbert Footner. Footner most successful creation was the beautiful and brilliant Madame Rosika Storey and her plain assistant who explains the evolving solutions to her boss’ cases. These stories take the reader to Morocco and China etc... Basically out of NYC where Storey resides. There’s lots of action and danger and disguises and very very bad people.
