About the author: Jacques Heath Futrelle (1875 – 1912) was an American journalist and mystery writer. He is best known for writing short detective stories featuring Professor Augustus S. F. X. Van Dusen, also known as "The Thinking Machine" for his use of logic. Returning from Europe aboard the RMS Titanic, Futrelle, a first-class passenger, refused to board a lifeboat, insisting his wife Lily do so instead, to the point of forcing her in. She remembered the last she saw of him: he was smoking a cigarette on deck with John Jacob Astor IV. He perished in the Atlantic and his body was never found. (wikipedia)

Mini-review:
The good: Cell 13 is always a good read. I thought I figured how the Stolen Rubens switcheroo was done, but I was wrong. The solution was surprising, although it requires some specialized knowledge about art. The Phantom Motor is a fun episode and a quick read.
The not-so-good: The Scarlet Thread was lacking both in motive and execution. The Flaming Phantom was an obvious setup from the start, the description of the home's interior gave it away.
