Regarding Lizzies comments about the Stash of Porn found under the Floor of Harris's Former Home.
In my then occupation as an Estate Agent, the firm I worked for at the Time In Beckenham, was given instructions to put the house in Sydenham on the Market, and I was sent to measure up the property and to prepare Particulars. when I visited the house Every Room was Stuffed Full of Paintings, by R,H and his Wife,also an Artist, Probably several hundred in total, when I again visited the House a week later, all the Paintings were Gone. We were told they had been moved to the Harris's new home.
If you could move several hundred paintings why not a clutch of porn? could that be the reason nothing was found.??
