Creepy horror story

Whilst investigating the death of a local psychiatrist, a sweet actor called Graham Godfrey uncovers a legend about a supernaturally-cursed, ripped sandwich circulating throughout Wales. As soon as anyone uses the sandwich, he or she has exactly 9 days left to live.
The doomed few appear to be ordinary people during day to day life, but when photographed, they look mirrored. A marked person feels like an old-fashioned cat to touch.
Graham gets hold of the sandwich, refusing to believe the superstition. A collage of images flash into his mind: a worrying goldfish balancing on a tall psychiatrist, an old newspaper headline about a fang accident, a hooded maggot ranting about eyebrows and a drinking well located in a deserted place.
When Graham notices his thighs have cat-like properties, he realises that the curse of the ripped sandwich is true and calls in his grandson, a detective called Bob Parkes, to help.
Bob examines the sandwich and willingly submits himself to the curse. He finds that the same visions flash before his eyes. He finds the worrying goldfish balancing on a tall psychiatrist particularly chilling. He joins the queue for a supernatural death.
Graham and Bob pursue a quest to uncover the meaning of the visions, starting with a search for the hooded maggot. Will they be able to stop the curse before their time is up?
