It should be noted that the entire canon of my own Solar Pons stories following the series written by the late August Derleth was commissioned and authorised by Arkham House USA back in the mid 1970s but for various reasons were withheld from publication and are only now appearing in their original form after some 30 years in limbo. Over the decades a number of editions with altered and mutilated texts have appeared. The definitive texts of the remainder of my canon can be found in the following:
The Further Adventures of Solar Pons (Academy Chicago, 1987 pbk)
The Dossier of Solar Pons (Academy Chicago. 1987 pbk)
The Exploits of Solar Pons (Fedogan and Bremer, USA, 1993 hbk)
The Recollections of Solar Pons (Fedogan and Bremer, USA. 1995 hbk)
Solar Pons Versus The Devil’s Claw (Sarob Press, Wales, UK, 2004 deluxe & limited edition, both hbk)
The Adventure of the Persecuted Painter in the present volume appeared in The Mammoth Book of New Sherlock Holmes Adventures, edited by Mike Ashley (Robinson Books, UK 1997 and Carroll and Graf, New York, USA. both pbk)
