Tread Perilously wraps up Doctor Who month with its 25th Anniversary story: "Silver Nemesis."

The Doctor and Ace's jazzy afternoon in Windsor gets interrupted by an alarm signalling imminent danger headed for Earth. Meanwhile in 1638, Lady Peinforte and her manservant, Richard, plan to travel 350 years into the future to recover a statue The Doctor launched into space some months before. Elsewhere, Herr De Flores plots to take the statue for himself and for "zee Fatherland." Is this all according to The Doctor's design? Or will another gaggle of shambling Cybermen throw off his calculations? Also, will the Queen recognize The Doctor?
