Maurice Blum 26, and his brother, Francis (Frankie) Blum, 31.

Maurice Blum was a businessman who owned several bookmakers shops as well as The 214 casino in Crystal Palace. His elder brother worked as enforcer-stroke-debt collector.

Mason Green had a system to "beat the book" and, with no-one really knowing, ended up taking the Blum's for £440,000.

The Blum's found out who was behind, these young girls on scooters, who had been putting these huge bets on, and planned to hurt him.

They went for both his Achilles heels, that being Gaynor and his gran - Ana Reung.

EPISODE 10

THE CRYSTAL PALACE MURDERS

Maurice Blum's Casino in Crystal Palace - The 214, gets hit by a few Hammersmith Faces who have used a mobile phone that Mason had rigged to get the gaming machines to continually pay out.

Although Mason didn't go to the casino himself, he has been on a spree of spread betting through several bookmakers shops in west London - four of which belong to the Blum's. Word has it that he has taken them for nearly £440,000.

Someone has spoken out of school and the Blum's make their play and the elder brother Frankie makes a sustained play on Gaynor, whose head gets turned.

Mason is one step ahead, however.

He has been tracking the phone activity of both brothers. Their big plan is to go for his other Achilles heel and that is to hurt his Gran.

That cannot happen.
