Beware of the Dog

The dog was old and unappealing - which may have been why Virginia Freer decided to adopt him; that and the fact that he had belonged to her mother's old friend Helen Lovelock, who had recently died. The tensions evident among the mourners at Helen's funeral soon erupt, and before long one of them is dead, and so is the dog. When Virginia calls in her ex-husband Felix, the Freers discover the death was convenient for several who attended the funeral.
But why should anyone poison the dog? Yet someone had - and therein lay the solution to the murder .
