The Riddle of the Yellow Zuri — Harry Stephen Keeler

In the open market in Chicago, a tiger snake could have been bought by a circus for $10. But the particular snake for which Jake Jennings was willing to pay a small fortune was the key to a great mystery. The grand climax is an absolute surprise, and no reader will be able to say, "I knew it from the beginning."

Here is fiction that is stranger than truth. It contains one of the most perplexing and labyrinthine mysteries ever conceived by the human mind.
