The Horror at Lavender Edge by Christopher Henderson
Harry Undine is psychic and its tearing him apart.
When his so-called gift kicks in, the pain can be deep and soul-wrenching - a pain nobody would understand, even if Undine revealed the truth. Which he won't. That sort of sensitivity might be considered 'cool' by hippies and New Age freaks, but its a million miles away from the tough Rat Pack image Undine aspired to when he was growing up.
So Undine keeps his mouth shut as he hunts for a cure- a personal quest more important than the research he is supposed to be carrying out as a paranormal investigator for the Corsi Institute.
Out in the suburbs, WPC Jo Cross is determined to do right by the terrified old lady she promised to help.
Jo approaches the Institute for assistance, and soon Undine's sixth sense is screaming a premonition of danger. But the location Jo describes is notorious, and the Institute team leaps at the opportunity to investigate Mitcham's most infamous haunted house. Undine cannot back out of the investigation, not without admitting his shameful secret.
Meanwhile, on the edge of South London, something more ancient and more horrifying than any of them could imagine has already begun to stir...
