I'm still doing research on American circuses in the first half of the 20th century, and on rural Hungary circa 1880 for my tiger play. Last week I read a mystery, The Search for Yesterday's Rings, by George Chesbro. I had never heard of the novel or Chesbro (he died in 2008). Chesbro's detective is a dwarf whose stage name is Mongo (from his days as an acrobat). Mongo and his brother run a detective agency in New York City. In an attempt to restore the Statler Brothers Circus to his former boss, Phil Statler, Mongo uncovers quite a circus. It's now run by two evil Swiss Germans, the Zelezians, interested in creating assassins for foreign governments. But these assassins have four legs- a recreation of an extinct canine, the lobox. These wolf dogs are deadly and scary, and Chesbro's plotting, if not always his prose, is excellent. It's a fast, creepy, interesting novel.
