A second post-steampunk adventure set in the New York of the 1920s, again featuring the vigilante called the Ghost. As last time, this is a straightforward action story, in this case 'shady cabal have horrifying ambitions and must be stopped'. That's pretty much what happens, and it's a brisk, pacy read. There is exactly one plot, and everything that happens feeds it. It helps the novel be what it wants to be - pulp action - but it's also a little empty. There's not much mystery to the story, and as little else is happening but the race to defeat the villains, it feels like a snack more than it does a meal. As a quick shot of steampunkish heroics spiced with Lovecraftian horror, it works, but I still prefer the far richer tapestry Mann creates in the Newbury & Hobbes series (set a few decades before the Ghost books).
