P. J. Tracy

P. J. Tracy is the pseudonym of an American mother-daughter writing team, Patricia "P.J." Lambrecht (April 18, 1946 – December 21, 2016) and her daughter Traci Lambrecht, both of Minnesota. Together they wrote the Monkeewrench crime-thriller series, beginning with "Monkeewrench" (2003, published in the UK as "Want to Play?"), and won the Anthony, Barry, Gumshoe and Minnesota Book Awards.

After Patricia's death in 2016, Traci Lambrecht has continued to write under the shared pen name alone, completing the Monkeewrench series and launching the Detective Margaret Nolan series with "Deep into the Dark" (2021).
