Tom Keels will be the guest on WHYY's Radio Times tomorrow morning (Thu July 1) at 11AM. Keels' new book, Wicked Philadelphia: Sin in the City of Brotherly Love was just released a couple months ago and features a chapter on Singleton Mercer's murder of Mahlon Heberton, the case which inspired George Lippard to write The Quaker City.
In January, Keels did a piece for WRTI radio about that murder and Lippard's novel, in which I was happy to participate. You can listen to that show here (the Lippard part begins at the 14:30 mark).
And check out Radio Times tomorrow morning.
