Toby's Folly: A Penny Spring and Sir Toby Glendower Mystery (Penny Spring and Sir Toby Glendower Mysteries)

Penny is looking forward to a lengthy visit from her son, Dr. Alex Spring, when she receives a summons from Scotland Yard. Where is Sir Tobias Glendower? It happens that a young Russian ballerina is being held in custody as a primary suspect in the bizarre bludgeoning-to-death of one of the members of a visiting Soviet corps de ballet. But she will speak only to Sir Toby, who she claims is her father! Toby is eventually reached at his private archaeological excavation deep in the Welsh country--the "folly" of the title--and plunged headlong into mayhem and danger.
