Secret Dead Men is an engagingly quirky fantasy/mystery by Duane Swierczynski. Originally released in 2005, this reformat and re-release from Titan Books came out 1st Oct 2024, is 320 pages and is available in paperback and ebook formats. It's worth noting that the ebook format has a handy interactive table of contents as well as interactive links throughout.
Instead of a seedy walk up office downtown, PI Del has a hotel inside his brain which houses a collection of conscious souls which he's collected. His main purpose at the moment is to chase down and dismantle The Association which was responsible for his own trip into discorporeal inconvenience.
The writing is, frankly, solid. It's action driven, but also full of well rendered three dimensional characters (including a stoner thief who comes out to hotwire the occasional getaway car, lots of criminals, and a few psychopaths). The plot is well constructed with a nice mystery which works very well given the intricate and creative world building.
It's not at all derivative, but there are glimpses of Philip K. Dick, Chuck Wendig, Stross, and even a bit of Joe Lansdale in the mix. There are moments of levity, although it's not primarily a humorous book, and there's over the top violence throughout.
Four stars. Well written, workable plot, nice mystery, solid characters.
