The occult detective theme has also been used with series characters devised by such contemporary writers as Douglas Adams (Dirk Gently), F. Paul Wilson (the Repairman Jack series), Steve Rasnic Tem (Charlie Goode), Jessica Amanda Salmonson (Miss Penelope Pettiweather), David Rowlands (Father O'Connor), Rick Kennett (Ernie Pine), Brian Lumley (Titus Crow), Robert Weinberg (Sydney Taine), Simon R. Green (John Taylor), Steve Niles (Cal McDonald), Mike Carey (Felix Castor), Mike Mignola (Joe Golem), Mercedes Lackey (Diana Tregarde), Laurell K. Hamilton (Anita Blake), Brian Keene (Levi Stoltzfus), Jonathan L. Howard (Johannes Cabal), and Jonathan Maberry (Sam Hunter). Jim Butcher's best-selling book series The Dresden Files is another well-known example. Randall Garrett's Lord Darcy stories and Dean Koontz's "The Haunted Earth" are examples in which occult detectives operate in a world where the occult is simply an accepted part of mundane life. Assaph Mehr's Stories of Togas, Daggers, and Magic combine historical mystery detective in ancient Rome with fantasy and occult elements.
