I’m on record as saying Anthony Horowitz’s Foyle’s War is my favorite television series ever, although I admit I’m sort of stretching the boundaries – like many British series, Foyle’s War is more like an ongoing sequence of made-for-TV movies, with each episode running about 90 minutes and with a completely self-contained story. The mystery series, starring Michael Kitchen as the marvelously taciturn DCS Foyle, ran for eight seasons across fourteen years, with 28 episodes set from 1940 to 1947. Horowitz wrote most of the episodes himself, crafting memorable three-dimensional characters along with tightly-plotted mysteries worthy of the greats of the genre.

Horowitz is also a successful novelist and has the distinction of being the first writer authorized by the estate of Arthur Conan Doyle to use the Sherlock Holmes and John Watson characters in a new work of fiction. (The characters are in the public domain in the United States, Canada, and the United Kingdom, so any author can use them in his/her works.) The second of his two novels in the Holmes universe, Moriarty, doesn’t actually include Holmes or Watson, but instead builds a new mystery around some secondary characters, including the titular villain who himself only appeared in one Holmes story, “The Final Problem,” where the two tangle at the Reichenbach Falls and appear to drop to their deaths. In the wake of that event, a leader of American organized crime appears to be moving into London to fill the void left by Moriarty’s death, and it is up to Scotland Yard Inspector Athelney Jones and Pinkerton detective Frederick Chase (who narrates) to try to track the killer down.

Moriarty doesn’t seem at all like Conan Doyle’s work; it’s fast, breezy, light on character, and frankly loaded with silliness, both poor work by Inspector Jones and overuse of graphic violence by Horowitz. Holmes is legend because he’s charming in his aloofness and impressive in his deductive powers. Neither Jones nor Chase brings an ounce of charisma to the book, while the various tough guys they encounter are garden-variety bimbos who could have left the pages of any pulp noir story to make a few extra bucks by appearing here. We even get the ultimate cliché, the scene where the protagonist (in this case, both of them) gets knocked unconscious and wakes up in captivity, to which Horowitz brings nothing new whatsoever.

To the extent that Moriarty works at all, it’s because of the Twist, and it’s a big one. Without that, this is a bad mystery or a bad detective novel. With it, well, it’s something. It might be a clever puzzle, but I felt like I’d been conned. The reveal includes references to some of the clues you might have picked up on earlier in the book, but not only did I not see them, nothing even tipped me off that I should be considering the possibility of a con. You can write an entire novel in the first person, and then open the last chapter with, “Whoops! I lied,” but that doesn’t make it a good novel. Give me a fair shot to figure out the truth and I won’t feel cheated when I fail to do so. Horowitz always did that in his TV work, but left that element out of Moriarty, ruining the work for me.

Next up: I’m still several books behind but am back on the Pulitzer trail with Julia Peterkin’s Scarlet Sister Mary, which won in 1929.
