But not directly before the murders because Pike saw it on the bench.
I can't find where he says that in his statement - he just said it was in the kitchen. He does say that Nevill unplugged the cordless phone though, so maybe the cream one got plugged in after that.
There is no photo of the "fawn" phone, so I can't say whether that could be described as "cream". Mr Pike did say that the phone he saw was of the type issued by the GPO.
