Every Pipes Sighting In BBC's 'Ghostwatch'

While roving reporter Craig Charles conducts an emotional interview with Pam Early around six minutes in, some viewers have spotted a figure outside the patio door behind Craig. The figure does look ominous in the dark, but upon closer inspection it's clear that this is actually just Craig's reflection. This is confirmed by the fact you see the double holding a microphone and turning as Craig does.

Some fans have speculated that Pipes might be lurking in a crowd outside at the 10 minute mark when camera man, Chris Miller, shows off his thermal imaging camera. We can see why people might think this. Most of the crowd have glowing eyes as this is a part of the body that loses a lot of heat, but one figure in the crowd seems to have black eyes as if gouged out. While this does seem like a possible match for Pipes, look closer and you'll see that the figure is enthusiastically waving like the other audience members, not stood deathly still as Pipes characteristically does. What people are actually seeing here is the cold lenses of an audience member's glasses.

Our first proper look at Pipes comes around 20 minutes in. In the studio Michael and his guest expert, Dr Lin Pascoe, re-watch some research footage shot in the house after someone phoned into the show to say they'd seen a figure in the clip. Upon seeing this footage the second time, a figure is clearly seen stood at the back of Kim and Suzanne's bedroom near the curtains. Frustratingly, Michael and Dr Pascoe can't quite make it out.

Later Lin gets a close encounter with Pipes when the studio lights are lowered as her and Michael listen to a recording made during her investigation of the case. As the pair stand next to the reel to reel tape recorder the menacing figure of Pipes appears over her shoulder, before once again fading into the darkness.

Just over three-quarters of an hour in, Craig is told about some of the horrific events that have occurred in Northolt by some locals. As he walks back towards the house to meet the "guy who tried unsuccessfully to exorcise Foxhill Drive," Pipes can be seen in the crowd where Craig meets the man he's interviewing, Arthur Lacey.

After thing seemingly start to kick off in the house, Sarah follows a trail of kids pictures that have been strewn across the kitchen floor. As she reaches an odd occult-like circle of crayons in front of the patio door, she is startled by a cat outside... but this isn't what she should really be scared of. When she stands up we see in the reflection on the glass door that Pipes was stood threateningly behind her the whole time.

A little while later at around the 70 minute mark, things have escalated in the house again. As the crew take Kim and Suzanne out of their bedroom, the camera man spots Pipes stood in front of the curtains as he pans the camera across the now-empty room.

Towards the end of the programme the whole house starts to shake and the camera zooms in on a mirror that's rattling on the wall. Some viewers think they can see the reflection of Pipes in the mirror. It's possible this was intended to be Pipes, but if that's the case then the shot didn't really work as it's impossible to tell if it's Pipes, the sound man Mike Aiton, or just something else creating a vaguely human-like shape.

After the crew remove the board from the door to the cupboard under the stairs, known as the glory hole, it slowly swings open, as it does, we get a very brief show of Pipes stood inside. This is after all the part of the house where Raymond Tunstall took his own life, an act that caused him to return to the house as the sinister Pipes.

At the climax of the programme, Sarah ventures in to the glory hole and the door slams closed behind her. Just after this some static appears on screen which shows a broken image of Pipes' face implying he was interfering with the broadcast.

Seconds later we get our final glimpse of Pipes, this time in the BBC studio in London. After inadvertently creating a mass séance, Pipes seemed to no longer be confined to Foxhill Drive and his influence over the until-now safe studio that housed Michael Parkinson was seen as a light explodes. As the remnant sparks fall to the studio floor, we see Pipes stood underneath the light on a gantry.
