A bizarre murder shakes a quiet Cornish village. Arriving at the church on Easter morning, the vicar finds the body of a woman sprawled across the chancel steps. To add to the horror, the church is filled with the discordant sound of an organ chord, the notes apparently chosen at random and wedged down.<BR>Has the church been desecrated by a Satanic ritual? Chief Superintendent Wycliffe sees the crime more as an expression of hatred deep within the community, but his investigation is frustrated at every turn, throwing up more questions than answers.<BR>Then another murder is committed, as shocking as the first. Wycliffe thinks he knows the killer's identity - but can he prove it?
