In this third roller-coaster historical thriller set in early 20th-century Detroit, from the author of The Detroit Electric Scheme and Motor City Shakedown, it is the summer of 1912. Car maker Will Anderson and his former fiancée and sometime-sleuthing partner Elizabeth Hume are called to the Eloise Insane Asylum outside of the city, where Elizabeth's cousin Robbie is a patient—and now a murder suspect, after the death of three victims in as many months. Elizabeth enlists the help of Detective Riordan to prove Robbie's innocence, finding a lead that takes them to Kalamazoo, while Will goes undercover, enduring horrific treatment as a patient in the asylum to help catch a killer—who may be much closer than anyone suspects.
"Johnson's excellent third mystery effectively employs parallel first-person narratives to advance an investigation into a creepy murder. Johnson makes the most of the spooky setting."—Publishers Weekly (starred review)
