Welcome to discussion Wood.
If you can, read The Suzy Lamplugh Story by Andrew Stephens.
According to David Videcette, Suzy's diary, chequebook and a postcard were recovered by the acting pub landlord on the Sunday night.
Upon instructions from landlord, the acting landlord phoned Suzy's bank on Monday morning.
Suzy rang bank too, presumably to cancel chequebook, and learned pub had them.
Suzy rang pub and headed at lunchtime to collect her items.
Suzy, the bank, Sturgis secretary and other pub staff knew the acting landlord had her items.
Acting landlord told police Suzy had arranged to collect items at 6pm. Suzy had a house viewing at 6pm.
Police recovered all items from acting landlord a day or two later.
Boyfriend Adam told police (and TV doc) Suzy's items where lost on Friday night?!
My guess is Suzy left items in the phone box she used outside the pub late Sunday night, and the items were then sat on an outside table where they were recovered by acting landlord.
If acting landlord had of just destroyed items, the police would have surely soon learned that he had them in his possession.
And if he had of said Suzy collected them and left, then that would have proved Suzy was at pub at lunchtime.
No he went for she was due at 6pm and didn't show up. All attention on Kipper / Shorrolds so he got lucky....
