While attending a conference in the
Netherlands, Mrs Bradley encounters an eccentric Dutch family including a young woman under pressure to marry her cousin, to the outrage of her handsome brother Florian. While Florian is sitting for a
portrait commissioned by his aunt in which he is holding a
delft blue object, he disappears. He subsequently reappears in the British
Peak District in
Derbyshire. Shortly afterwards two local
barmaids die after eating poisoned chocolates which may have been intended for Florian. ==References==
