The Spectre is a novel about a criminal profiler hunting a serial killer, akin to The Silence of the Lambs, which is not an uncommon genre but The Spectre has some features which few other novels in the genre have: the story is set in the future, 2133, akin to Blade Runner and The Spectre is a mystery thriller, similar to the Sherlock Holmes mysteries. The identity of the killer is not revealed until the end of the book, very much like the Agatha Christie whodunnits, and there is a surprise ending to rival Psycho.
Blackmoor, the profiler and central character of The Spectre, is a dominant in the BDSM scene akin to Christian Grey, the central character in Fifty Shades of Grey.
