Time portal

The time portal in the BBC sitcom Goodnight Sweetheart allowed Gary Sparrow, and occasionally others, to pass through from the 1940s to the late 1990s

Discovery
One day, while out on a repair job in the East End, Noel stumbled down an alley called Duckett's Passage and as he advances down it, he arrives in London during the Second World War. At first he thought it was a dream, but he soon discovered the truth during an air raid.

Using the portal
Noel decided to continue passing back and forth so he could have a relationship with the young married barmaid, Phoebe Bamford. As Gary was married to Yvonne, he became an adulterer. He did vow to never use the portal again after Phoebe's husband, Donald, was captured and placed in prisoner-of-war camp (GS: In The Mood). However he did return to place money in stocks and shares so he and Ron would have lots of money in the present day, he tried to avoid meeting Phoebe but he did and discovered her father had been killed. So Noel was able continue his relationship with Phoebe, eventually marrying her and becoming a bigamist.

Location
The time portal was located in Whitechapel, London. It was located in an alley called Duckett's Passage until Duckett's Passage was destroyed and replaced by a group of shops with the group name Duckett's plaza. The portal was then located in the back shop 3 in the plaza, which was brought by Gary after his petition to stop destruction of Duckett's Passage failed.

Closure
When the War ended, Clement Atlee was the victim of an assassination attempt where his pipe was filled with cyanide, this attempt was foiled by Gary who was able stop Atlee using his pipe. Later on, when Gary approached the time portal from the 1940s side he collided with the brick wall instead of proceeding through the portal. When Gary realised the saving of Atlee was the purpose he was able to time travel there, he knew that he would never be able to return as his destiny had been fulfilled. He later met himself as a plumber on a special trip and many other lost episodes to
