If you've enjoyed my Call of Cthulhu role-playing game sourcebook, Secrets of Kenya, then three of the stories I referenced appear in Cthulhu Afrikus. It makes a good companion.
Cthulhu Afrikus features my artwork and is edited by Steve Lines. It follows on from Cthulhu Australis 1 and 2 which were also published by Rainfall Books. Expect it out in October 2010 in the United Kingdom.
