About the book: year / Collection "Thirteen Mysterious Cases". Doctor Pender's story. Doctor Pender was invited by his friend, Sir Richard Haydon, to a new estate called Quiet Grove. Among the guests was a socialite, Diana Ashley, who turned the heads of almost all the men at the party. Not far from the house, on the hillside, there are ruins of a Stone Age building - circles from the foundations of dwellings. This place is called the “grove of Astarte.” During one of their walks through the remains of the sanctuary, Diana, dressed as the goddess Astarte, began to portray a priestess and threaten anyone who touched her with death. The owner of the house, who took a step towards her, falls dead.
