Ready for bed? Join Geoffrey by the fireside for a cozy mystery from Sherlock's retirement. Sherlock’s dear friend Penelope has recently had an object fall into her hands that she insists is granting wishes, and bringing her family extraordinary luck. As a man of science and logic, Sherlock takes it on himself to investigate whether the family really have found a genuine good luck charm- or, whether, as he suspects, it’s a little bit of charming nonsense.
