When Charlotte Elkins was the American Art librarian at the de Young Museum in San Francisco, she took a fling at writing a romance in her spare time.. To her surprise, it was accepted by a major publisher. She then went on to write four more romances under the pen-name Emily Spenser. all of which were published in more than twenty countries. But soon she found that collaborating with Aaron on mysteries was a lot more fun, and the first Lee Ofsted novel, A Wicked Slice, was the result. The authors, encouraged by the reception from reviewers and fans, went on to collaborate on four more Lee Ofsteds. In between, they put out the occasional short story, one of which, “Nice Gorilla," won the Agatha Award for best short story of the year in 1992.
More recently, Charlotte has been working with Aaron on their mystery series about the "Art Whisperer," Alix London, in a venture that takes Charlotte back to her roots in the world of fine art.
