About the Butterfield Institute series
Dr. Morgan Snow is a sex therapist at Manhattan's Butterfield Institute whose clients' most private confessions keep pulling her into criminal investigations she has no formal standing to run -- a premise M.J. Rose uses across three novels to fuse psychological thriller plotting with frank, unflinching engagement with sexuality and its darker edges. The Halo Effect (2004) opens the series when one of Morgan's patients, a young sex worker, is murdered shortly after a session -- pulling Morgan into a case the police are reluctant to take seriously. The Delilah Complex (2006) follows a support group Morgan runs for men and women obsessed with dangerous sexual fantasies, one of which appears to be turning lethally real, while The Venus Fix traces an online sex-addiction ring back to a string of increasingly disturbing crimes.
Rose, who researched the sex-therapy world in detail, uses Morgan Snow's clinical perspective to treat her characters' desires and traumas as psychologically real rather than as thriller shock value, a combination that drew comparisons to Jonathan Kellerman's psychologist-detective novels while carving out a distinctly franker, more sexually-explicit space of its own.
