Tread Perilously finally delivers the long-promised month of crossovers, starting with the Magnum P.I./Murder, She Wrote event -- "Novel Connection" & "Magnum on Ice."

When Robin Masters' latest house guests appear to be marked for assassination, Higgins does everything in his power to dissuade Magnum from digging into the case. As it happens, Masters' agent has brought in help of her own: Jessica Fletcher. And while Magnum keeps saying he doesn't want the case and Jessica maintains she is no investigator, the pair end up looking into the problem once Magnum stands accused of murdering a local he insists is the contract killer hired to kill one of the guests.

Erik and Justin plot a "Crisis of Infinite Podcasts." They also take another look at both Magnum and Murder, She Wrote as different types of detective shows. Higgins' absolute fascination with Jessica proves to be the crossover's greatest asset -- and that's considering the presence of Jessica Walter in the guest cast! The strange ending of the Magnum episode leads Erik to suspect a "safety" conclusion was filmed for syndication. The mystery of Robin Masters is once again explored. Wolverine proves to be a bad man. Tom Selleck's leading man quality is appraised and Ronny Cox leads the "untrustworthy screen presence" chart.
