Ok, I am trying to understand PS's movements that day...
IMOO
- So he went for his usual morning walk, but does not remember if his wife went with him - was it on this particular day he spoke to the lady in the caravan?
- He comes home and in no particular order: had something to eat on patio, heard kids playing, made 2 phone calls, packed his bag
- His wife then leaves at 10.37am for bingo
- He decides to make another light meal before his scheduled departure at 11am- he has the radio on (not sure if I have this correct)
- Then a knock at the door from his neighbour.
- He goes to check neighbour's house who was away and goes up the hill
