Let me explain it to you again.

Bill, my friend of seven years, lies face down in the sand on the beach. He was found just after sunrise as the tide headed out. His clothes and hair were wet.

There were five stab wounds to his stomach. His wrists were bound together and a rope was tied around his ankles, and the other end was frayed.

His wallet is gone, and he was a billionaire businessman at 27. He had no wife, very few friends and all his assets went to his best friend in university who gave him the business idea in the first place.

And yet you, a detective, say Bill’s death was caused by a serial killing vampire?
