Trivia / Freeman Wills Crofts

• Technology Marches On: In The Hog's Back Mystery, the solution relies on the fact that one character had borrowed another's car without his knowledge. A modern-day reader would be far less likely to think of this, since they would have assumed the car couldn't be started without the correct key — in fact, ignition keys weren't invented until 1949.
• Write What You Know: Crofts made full use of his knowledge as a civil engineer — particularly in Death on the Way, which is set on a railway construction site.
