Towards ZeroWhat is the connection among a failed suicide attempt, a wrongful accusation of theft against a schoolgirl, and the romantic life of a famous tennis player? To the casual observer, apparently nothing. But when a house party gathers at Gull's Point, the seaside home of an elderly widow, earlier events come to a dramatic head. As Superintendent Battle discovers, it is all part of a carefully laid plan--for murder. Ordeal by Innocence According to the courts, Jacko Argyle bludgeoned his mother to death with a poker. The sentence was life imprisonment. But when Dr. Arthur Calgary arrives with the proof that confirms Jacko's innocence, it is too late--Jacko died behind bars following a bout of pneumonia. Worse still, the doctor's revelations reopen old wounds in the family, increasing the likelihood that the real murderer will strike again.
