Mark Question in "The Lord of the Shoes"

Mark Questin was a private detective. Just a normal guy with a normal firm—looking for runaways and domestic cases. But Mark has one special field of knowledge—he is an expert in folklore and the occult. He gets the weirdest cases and is known as Mark Question—Paranormal Investigator. When Mark gets a call on a murder/suicide, he knows something is fishy. There are few clues, and fewer unanswered questions; and the only thing different is an unusual, anonymous Renaissance painting.
