The affluent owner of a historic steam locomotive and private railcar disappears with millions of dollars belonging to Moose county investors. Journalist-detective Jim Quill probes the embezzlement with the aid of his Siamese sleuths, Koko and Yum Yum. The case is complicated by a train wreck and a murder in a railroad tavern. By the author of The Cat Who Could Read Backwards, the book which launched the 17-volume series in 1966.

UFOs in Mooseville? Rumors abound that a missing backpacker has been abducted, and it looks like Jim Qwilleran's sedate summer may be interrupted by an investigation -- with the help of his own little aliens, Koko and Yum Yum. And when the backpacker's body turns up -- and transplanted Floridian Owen Bowen is found dead soon afterward -- the search for intelligent life turns into a close encounter with a killer.
