One other comment on the review -- I'm delighted that you found Innsmouth so vivid that you thought it was based on a real place! Still, let me 'fess up -- I used Lovecraft's very detailed descriptions in "The Shadow over Innsmouth" and a good clear street map of Innsmouth drawn by Joseph Morales, which you can find here, and spent quite a bit of library and internet time getting the flavor of a decayed New England seacoast town. (I've always appreciated the kind of fantasy fiction where the author takes the time to make the setting vivid and believable, thus my efforts in that same direction.)

Oh, and putting the Esoteric Order of Dagon in an old Masonic hall was Lovecraft's idea, not mine. Still, the Masons I know will appreciate your shout-out. ;-)
