...What secrets has the torn slip kept since December 1st, 1948?...
It's a reasonable question to ask is it not? This slip contains more than one secret and in this post, we'll examine just one of them, but first a question...
Supposing it was you heading for the beach at Somerton on 30th November 1948, perhaps you were being pursued and perhaps not but whatever the case, you had made a decision to hide this small slip of paper that for some reason you had decided to tear out of a copy of the Rubaiyat of Omar Khayyam.
Today we are thinking about the process that the man used to hide this slip. Freshly removed from the page of the book, he had chosen a good hiding place, according to the Adelaide Wiki on Leonard Douglas Brown, the hiding place was a 'secret pocket' and the nurses's phone number was written on the back of the book in 'really tiny lettering'. This is the website link to that page:
So, the decision to hide the slip and just where it was to be hidden, has been made. First, he would roll the slip up very tightly, (so tight in fact that Cleland had to use a pair of tweezers to extract it from its hiding place) and then he pushed the rolled-up slip hard down into the crease (seam?) of the pocket such that a cursory pat down would confuse the slip with the seam. All done?
Not quite. The question I have for you is straightforward enough. If you were to roll the slip up tightly and conceal it, what steps would you take to stop the rolled-up slip from unfurling and thus risk revealing its presence? Think about it a second or two which is probably what he would have done.
Spit. Not a comment, that's what he likely would have done, he would have used saliva to hold the slip together knowing that as it dried it would help bond the paper and keep it in its rolled-up state.
DNA
Here's the thing, there are basically two kinds of DNA that can be retrieved from paper, touch DNA, such as you obtain from fingerprints for example, and DNA from bodily fluids as in Saliva. The latter is of most interest because touch DNA deteriorates in a matter of weeks or perhaps a little longer, and would no longer be a viable option for recovery of the same.In contrast, saliva from the backs of postage stamps and envelope flaps has yielded good-quality DNA samples from as far back as the 19th Century. Here's one link but there are more:

Consider that concealing this rolled-up slip of paper could probably have been the last thing he did before puffing his last cigarette.
The search now switches to a hunt for the slip wherever it may be.
I am amongst those who missed this, so I can't claim immunity but I found it eventually, in recent times in fact. However, there are far better-qualified people than I, leading academics amongst them, who should have had a handle on this years ago but it is not the case. How come?
Oh Yes! Bloody Brilliant!
