Wife 'bugged'
Mr Ellerbeck lived with their two children in Enfield and "on the face of it had everything - a nice house and a private education for the children".
But both he and his wife had embarked on affairs, the prosecution said.
Mr Brown said: "During the last few years their son, a very promising tennis player, had been coached at the local tennis club by Patrick McAdam.
"Kate Ellerbeck herself also used the club. But her friendship with McAdam over time turned into something deeper and they began an affair.
"She also was intimate on one occasion with a friend she had known for many years."
The court was told that the infidelity was the spark that led Mr Ellerbeck, a "controlling, jealous and secretive man", to bug his wife and later commit murder.
He bugged the home telephone and used specialist gadgets to monitor text messages sent from her mobile phone.
Police found 127 hours of tape recordings on a memory stick at Mr Ellerbeck's Canary Wharf office.
They included a conversation between his wife and Mr McAdam discussing their physical relationship.
Mr Ellerbeck denies murder.
