I had to pretend to be a police officer from the missing children's unit to reassure him that there are currently no missing children reports on the national database.
He has been obsessing for 2 days now about having to go and collect a child who was waiting by the river. He can't explain more than that they would have to "jump the queue" to get to the river and that the child comes from a "sporting family". He tried to get up in the middle of the night last night to collect this child.
He had such an incredible, exceptionally intelligent mind until a combination of old age and Parkinson's has clouded it. About a month ago, he suffered some sort of deterioration that affected his physical abilities, but this is the first time his mind has gone for so long and so off track.
It was the longest I have spoken on the phone with him for probably over a year (he struggles with his hearing aids so this call was a real effort).
He didn't see through my slightly put-on deep voice or the improbability that there are currently no outstanding reports of missing children on their database.
He had no idea he was talking to me.
