That said, <img src="graemlins/a_smil17.gif" border="0" alt="[blabla]" /> I am as curious as George in knowing the details, that unless we come across a manifest, we won't ever know.
If I was private Eye, I'd find out what ship he came on and see if it was on the manifest. But then, I imagine he would have carried them in his personal luggage, so unless there are notes from observers, we just have so little to go on.
