Wheeler's and Webb's first collaboration was published in 1936. That same year, they introduced two new pseudonyms: Murder Gone to Earth, the first novel featuring Dr. Westlake, was credited to Jonathan Stagge, a name they would continue to use for the rest of the Westlake series. A Puzzle for Fools introduced Peter Duluth and was signed Patrick Quentin. This would become their primary and most famous pen name, even though they also continued to use Q. Patrick until the end of their collaboration (particularly for Inspector Trant stories).
In the late 1940s, Webb's contributions gradually decreased due to health problems. From the 1950s and on, Wheeler continued writing as Patrick Quentin on his own, and also had one book published under his own name. In the 1960s and '70s, Wheeler achieved success as a playwright and librettist, and his output as Quentin Patrick slowed and then ceased altogether after 1965. However, Wheeler did write the book for the 1979 musical Sweeney Todd about a fictional London mass murderer, showing he had not altogether abandoned the genre.
