Tread Perilously keeps another promise as Justin finally gets a chance to watch the Doctor Who story called "City of Death."

When the randomizer lands The Doctor and Romana in Paris, 1979, they soon experience a time slip. It leads them to the Louvre, where a plot to steal the Mona Lisa is more than just a plot to steal a priceless painting. Shortly thereafter, a detective named Duggan joins their band as they learn the truth behind the plot, the fabulous wealth of Count Scarlioni, and the origins of all life on Earth.

Drew Siragusa of Fanbase Press joins Erik and Justin for a story he's wanted Justin to watch for many years. The old io9 Doctor Who story rankings re-emerge as "City of Death" rates quite high. Justin discovers on air that Douglas Adams mainly wrote the episode. He also reveals his favorite companions. Tom Baker's revised costume gets reviewed. So does Romana's costume. Drew tries to determine when The Doctor started dropping names of historical figures. Chandler's Law gets invoked. Julian Glover receives nothing but praise as Count Scarlioni. James Bond connections abound. Duggan proves to be a good companion for Romana and Erik mispronounces "Scarlioni" throughout.
