A large and valuable diamond has been stolen from the California home of billionaire muscle man and film star, Artemis Lenkoran. The diamond, known as the Nur-i-Dunya or 'Light of the World' was kept in a special display case in Lenkoran's Beverley Hills mansion. It was protected by a special laser alarm system.
Lenkoran lives in the mansion with his girlfriend, Ms Rita Chevrolet, and his servant, Oddjob.
Oddjob noticed the diamond was missing at 7 am on Monday morning when he made his morning rounds. The laser alarm had been disabled by cutting the wires. Lenkoran went to bed at ten saying he felt tired. Rita Chevrolet was at a party in Hollywood and says she returned at 1 am Oddjob worked out in the gym until midnight and then went to bed.	

There were no finger prints.	
A bathroom window to the rear of the house was broken.	
Oddjob is known to be a compulsive gambler with a sick mother in Miami.	
A black sports car was seen driving away from the house around 4 am.	
A pair of wire cutters was found in Oddjob's room among other tools.	
Oddjob thinks he heard a noise at 4 am. but assumed it was Rita.	
Another guest at the Hollywood party that Rita went to, says she left at 3 am.	
An investigation of Oddjob's bank account shows a recent deposit for $100,000.	
A diagram of the alarm system was found in Lenkoran's desk.	
Rita's in-box contains this email:  'Rita, baby. Thanks for a great evening. Tomorrow? Signed 'Zak.'  It's dated the day after the robbery.	
A handwritten note was found hidden in Lenkoran's study saying 'Fifteen million, Lenkoran...or I'll tell all'	
A journalist in Rome claims to have seen Lenkoran coming out of a famous gay club a month ago.	
Some fragments of broken glass were found on Lenkoran's clothing.	
Lenkoran recently increased the insurance on the diamond from five to fifteen million dollars.	
A possible solution	

Lenkoran might have been gay. If so, he may have wanted to keep this a secret. But Oddjob must have known about it - after all, he was living in the same house.

Oddjob must have needed money - his mother was sick, he was a gambler and personal servants don't earn that much, so he could have been blackmailing Lenkoran. The $100,000 deposited into his bank account may have been money he received from Lenkoran to keep quiet.  If that was the case, Oddjob might have then got greedy, or he might have needed more money to cover his gambling expenses or his mother's medical care and asked for more.

Lenkoran must have increased the insurance premium with a view to committing a fraud by staging a fake burglary. This would explain the fragments of broken glass and the diagram of the alarm system in his room. He might have planted the wire cutters in Oddjob's room in an attempt to direct suspicion towards his servant, or the wire-cutters might have been there for some other quite innocent reason.

As for Rita, she probably wasn't involved in the plot. Her relationship with Lenkoran is interesting, however. She could have been  'a front' to cover the fact that Lenkoran was gay, or Lenkoran may have been bisexual. Whatever she she must have had a lover and she must have been lying when she said she returned at 1 am.
