Lay Death at Her Door — Elizabeth Buhmann

Twenty years ago, Kate Cranbrook's eyewitness testimony sent the wrong man to prison for rape and murder. When new evidence exonerates him, Kate says that in the darkness and confusion, she must have mistaken her attacker's identity.

She is lying.

Kate would like nothing better than to turn her back on the past, but she is trapped in a stand-off with the real killer. When a body turns up on her doorstep, she resorts to desperate measures to free herself once and for all from a secret that is ruining her life.
