Sherlock Holmes and Dr. Watson have passed into the public domain, so, for the most part, authors are free to do with the characters what they will... and, judging from the large number of Holmes-based fiction on Amazon, today's versions of Arthur Conan Doyle have explored just about every possible permutation of the Holmes legend. Sadly, few of them get the character and the writing just right, as witnessed by David Fessenden's amiable but not-that-mysterious of a tribute, "The Case of the Exploding Speakeasy."
Fessenden does a number of things right in this book. Sherlock and Dr. Watson are dead, but Fessenden is able to credibly move the Holmes mythos forward in time to the American Roaring 20's by having as his narrator, Thomas Watson, son and heir of the late Dr. John Watson, who is now in Philadelphia trying to make it as a newspaper reporter. There's a more familiar Holmes here, the late Sherlock's brother Mycroft who pays the young Watson a visit in his official capacity as the executor of John Watson's estate.
Mycroft's timing is propitious, as he arrives just as the young Watson catches his first professional break when he's an eyewitness to the titular crime... an explosion in an illegal saloon in which the owner is killed. The police and the newspaper's more experienced reporters are willing to chalk it up as another mob hit, but Thomas interviewed a waiter at the club whose version of the events made it appear most unlikely that the explosion was mob-related. Thomas is determined to get the real story to help get himself promoted out of a career writing obituaries for the paper.
Fessenden has Doyle's writing style down fairly well, and a casual reader skimming through a couple of pages of this book could well think it was an actual Doyle work. However, Doyle was also a genius at creating compelling mysteries (people today still fondly remember tales like The Hound of the Baskervilles and The Speckled Band). Unfortunately, while the crime in Speakeasy could easily come from a Holmes tale, the mystery in the book more closely resembles the pilot episode for a cable television drama than a true Holmes mystery. It should be obvious almost immediately who the killer must be, but Thomas Watson's detective skills are much closer to Barney Fife's than even the limited skills of his own father. It's up to Mycroft to save the day, but he, instead, allows Watson to blunder right into the killer's grasp before sending someone in to rescue Thomas.
Fessenden may be setting the stage for a series involving Thomas Watson, as he carefully gives the young journalist a love interest and some rivals at the newspaper. However, Fessenden will have to do a lot more work in future books to give these characters more depth. Watson is a likable lightweight and Mycroft a drowsy substitute for his brother. The byplay between the two of them is considerably more difficult to pull off than what Doyle faced due to the age difference, but Fessenden's attempt to create Holmesian dialogue between this pair amounted to little more than sitcom level squabbling.
Reading "The Case of the Exploding Speakeasy" brought to mind a number of classic Holmes tales... as long as I didn't start paying too much attention to the actual story. Then, it brought to mind a number of not-so-classic TV mysteries. True Holmes fans may appreciate the book for its admittedly original twist on the original characters, but most others may wonder what these new characters are doing in the middle of such a routine mystery.
