Matthew Iden is the author of seven books in the Marty Singer mystery series and several acclaimed standalone novels, including the dark psychological thrillers The Winter Over, set at the South Pole, and Birthday Girl, featuring a homeless forensic psychologist. Before turning to writing he held jobs with the US Postal Service and an international non-profit, logged a short stint with the Forest Service in Sitka, Alaska, and spent 100 days circumnavigating the globe with the Semester at Sea program...where he once fixed Archbishop Desmond Tutu’s email. The Bitter Fields, Matt’s seventh Marty Singer mystery, was released in October 2019.
