I find it difficult to pick a single "Doctor Who" series as my favorite, but this one is definitely among those I can enjoy repeatedly. Tom Baker’s portrayal of the character alongside Elisabeth Sladen's “Sarah Jane” arrives in Edwardian England after being diverted from their intended course, as typically happens. Almost immediately, something feels amiss, because a grand estate seems to be emitting an unusual energy signature. Simultaneously, Egyptologist "Scarman," played by Bernard Archard, has explored a forgotten tomb and is now essentially a shell of his former self – under the control of the malevolent “Sutekh,” who had been imprisoned for countless years by Horus to prevent him from destroying everything. Employing an army of robotic mummies and manipulating "Scarman," he’s set on freeing himself, and it's only the Doctor’s intelligence that offers a potential solution. These narratives always shine brightest when they draw upon authentic mythology, and what could be better than incorporating ancient Egyptian beliefs with advanced technology? This also features my favorite villain and costume encountered by the Time Lord so far. Sladen proved to be a capable companion, and the series is further enhanced by Peter Copley’s performance as “Dr. Warlock” and Michael Sheard's portrayal of "Scarman’s" sibling, who happens to be a helpful amateur scientist. It delivers a considerable amount of suspense and certainly inspired me to research Egyptian mythology back then – I must have been around eight years old! I still remember the solution to the puzzle presented near the end, even today. It was genuinely entertaining.
