In Suffolk, he reunites the son with his family, but soon one of them is found dead, and preventing the theft of the chalice must be combined with solving the mysterious death.

After a mysterious chain of events, he is plucked out of danger by Albert Campion, who explains that a conspiracy of art collectors and criminals hopes to steal the treasure his family is charged with protecting.

With Val's 25th birthday, at which a great secret will be revealed to him, fast approaching, Campion and the Gyrths smuggle the chalice to London, evading ruthless crooks.

Awaking after his long night in the woods, Campion learns that his flat has been attacked, the chalice taken and Val Gyrth vanished in pursuit.

Later, the chalice arrives by post, and Penny and Beth find Val in a field, bedraggled and exhausted but alive, with a White Campion in his buttonhole.

Realising he knows too much, she pushes him through the floor into a stable with a wild, angry horse; he hides in a hay-feeder until rescued by Professor Cairey, who heard Daisy's name from the Munseys too.
