Ricin acts by breaking down proteins within cells, causing them to cease to function. There is no antidote to the poison, which is swiftly metabolized in the body, leaving no trace. It is, however, identifiable by its effects, which are incurable. In Tiger Dey's case, these progressed to repeated vomiting and bloody diarrhoea. Within two days his kidneys, liver and spleen would all collapse.

Dey's semi-legendary status, the controversy that surrounded him and the gruesome predictability of his demise attracted the kind of blanket media coverage that Dubai's rulers do not particularly enjoy. Outside the hospital, cameramen and reporters jostled for position. Inside, Dey's doctors tried their best to ease his pain. That aside, there was nothing they could do. There are few good ways to die, but this is arguably one of the worst.

Khat, whose given name was Kajoshaj Bajrami, met a swifter, more merciful end. He was shot in the back of the head, at point-blank range, when he went to collect his car in the lot behind the Karama Pearl hotel. No one heard the silenced shots or saw his assailant. His wallet was missing, however, and several witnesses testified to the fact that Khat had spent the evening at the bar in the basement club, boasting to anyone who would listen that he had just taken fifteen thousand euros in cash off Tiger Dey for a whore he'd bought for less than three thousand and was past her best earning days. The motive for his murder was therefore obvious, even if the culprit was, as yet, unknown.

At around 1.55 a.m., the man who had called himself both Samuel Carver and Pablo stopped by a dumpster behind a fast-food restaurant in the Deira district just north of the airport. He deposited a brown wig within the dumpster, making sure that it was well covered by a thick pile of stinking waste. He had already flushed his green contact lenses down a lavatory and swapped his white shirt for a black one. Back with his natural colouring of deep red hair and icy blue eyes, he made his way to Dubai International. Having checked in online and carrying only hand baggage he was in plenty of time to walk straight through security and on to the 2.45 a.m. Emirates flight to London. His ticket had been issued in the name of Damon Tyzack.
