Gibber,
Put simply, if this is possible, Raoul is (was?) a gay Brazillian dwarf who used to hide in the boot of H's Jag and be smuggled past security. I don't think he had a passport, he was too short to have his photo taken in the booth.
Anyway he used to perform terrible sexually degrading acts upon poor H, once involving an angle grinder I seem to remember. Raoul has been missing now for a couple of years. The police investigated, H was interviewed, but nothing could be proved. No corpse has ever been found. There have been sightings rumoured, once lurking around at the back dressed as a 1960's racing driver after the Royal Varirty Command Performance, but he is our own Lord Lucan and not mentioned in polite circles.
I can't tell you any more, I know nothing. Zip! Nadda! Zilch!
