Oh yes! I Spy Something Bloody is now available in audio. The story is narrated by Alexander J. Masters, who I think does a brilliant job of capturing Mark's gently malicious and often cold-blooded voice.
Even better, for three dollars more you can buy the complete collection of I Spy stories. In From the Cold is also available!
Given how really cold and ruthless Mark can be, I find his attachment -- his adoration -- of Dr. Stephen Thorpe one of my more romantic pairings. The stories are quite romantic.
Anyway, here they are -- available for your listening pleasure. I do hope you enjoy them!
