Chiller-lovers will not be disappointed with this nail-biting page-turner about three women who are stalked by the same nutter, who sends them death-threat letters and other nasties including the odd razor blade.

Tension builds effectively as each woman describes her feelings in the first person in three separate sections, although each story is linked by bringing in the same investigating officers and north London location.

The killer has his say every now and again, as he describes to the reader his observations of his victims as he gets closer to bumping them off. It's frightening stuff.
