On the night of Mr. Melvyn's murder, Lucien Freud was looking in vain for a bookie to take his bet on the big fight. As he'd gotten home from a hard day of book-signings and talkshow-appearances, he'd found a message from his half-brother, Harold, on the answering machine, telling him to bet all his money on Tyson, because the fight had been fixed.    He had been very eager to comply, but his search for a bookie had been to no avail.    So he'd given up in disgust, and decided to go catch the Hunter S. Thompson-flick, Fear & Loathing in Las Vegas, instead even though he'd heard that Johnny Deep wasn't that convincing.
