Part of the Library of Congress Crime Classics series, ‘Last Seen Wearing’ is a police procedural from an era in which apparently police were not constrained by search warrants, Miranda warnings, or other civil rights protections that shape today’s crime fiction. It’s hard not to think about how many real-life crimes were “solved” by police running rough shod over innocent people’s; witness the relentless interrogation of one young woman in this book who is only a witness. The plot is simple: college student Lowell Mitchell disappears from her dorm room at lunchtime one day in March, and is never seen again. Has she met with foul play, or is she a runaway or a suicide? It is not a spoiler to say that Det. Frank Ford quickly decides she’s “in trouble” and that becomes his chief avenue of investigation. There’s some clever deciphering of diary entries and lots of intimidation of suspects and witnesses; Lowell’s poor parents don’t get the kid glove treatment. Interesting as a period piece, but, wow, what a world to inhabit.
