[Doctor Sax]

Troo's design looks like the sort of book you would see sitting on a bookshelf. I think you should go with that, meself. I take your point about Fred Bartlett, though - you don't want to pick up readers who think they're getting the latest adventures of a genial Bassett Hound who usually makes weak jokes in a right-wing rag. "Psychic Detective", on the other hand, is overused to the point of cliche. Amazon uk chucks up 37 books with the phrase in the title. Perhaps you need to coin your own "psychic detective" style word, like Brian Lumley's Necroscope, maybe. Fred Bartlett - Psytech. Although that sounds a bit SFy.
