Five, Ursula P. Archer

A series of co-ordinates tattooed on the feet of a murder victim lead the police to a box containing body parts -- and a note from the killer with a series of cryptic clues to the identity of the next victim. A nail-biting, page-turning thriller that will send shivers down your spine.
     Every corpse is a clue.
     A woman is found murdered in a field. Tattooed on her feet is a strange combination of numbers and letters. 
     Detective Beatrice Kaspary quickly identifies these as map co-ordinates, which lead the police to a 'treasure box' containing several severed body parts -- and a note from the killer with a series of cryptic clues to the identity of the next victim. 
     So begins a desperate scavenger hunt in which Beatrice herself becomes a pawn in the killer's game of cat and mouse, as she risks all to uncover the murderer.
