S2E19 The Case of the Caretaker's Cat

Title: The Mystery of the Caretaker's Cat Plot: Affluent Peter Baxter devises a plan to gauge the fidelity of his heirs by feigning a will alteration that bequeaths his fortune to his groundskeeper, James Hing. Under the pretense of a sinister plot, Hing is tasked with setting fire to Baxter's mansion while Peter swaps his own body for a medical cadaver. Should any heir challenge the new will, they would face disinheritance. Hing follows through with the plan, but the charred remains found in the wreckage turn out to be Peter's. Now, Perry must untangle this complex scenario and unveil the truth.
