An "obsessive" killer who tortured and murdered a rare books dealer for a £50,000 first edition copy of the children's book the Wind in the Willows has been handed a life sentence with a minimum of 34 years.

Michael Danaher, 50, stabbed to death Adrian Greenwood after going to steal his 108-year-old copy of Kenneth Grahame's classic book.

The 25-stone killer had compiled a "clinical" spreadsheet list of potential high-value targets for theft, robbery and ransom demands, including supermodel Kate Moss and author Jeffrey Archer.

It also included Mr Greenwood, aged 42, whose body was discovered by his cleaner inside home in Iffley Road, Oxford, the day after the killing.

Heavily indebted Danaher took the Wind In The Willows book from the murder scene and put it up for sale on eBay the following day, the trial heard.

Handing down a life sentence, Judge Ian Pringle QC said that Mr Greenwood was subjected to a carefully-planned and "savage" attack that left him with at least 16 stab wounds.

There was also evidence of torture from numerous "persuasion marks" made with a knife point.

The court heard that Mr Greenwood had suffered more than 30 injuries including stab wounds to the throat and chest and a broken arm that may have been caused by being stamped on.

Danaher, who was £13,000 in debt, had also searched online for the homes of TV presenters Eamonn Holmes and Michael Parkinson, footballer Rio Ferdinand and music mogul Simon Cowell.

Former FA chairman Greg Dyke and commentator Katie Hopkins were also included in his online searches, the court heard, as was "Louise Redknapp house" and "Lineker house".

Police investigating the death of Mr Greenwood later discovered the murder weapon and bloodied boots at Danaher's home in Hadrians Close, Peterborough.

The killer had claimed at Oxford Crown Court he acted in self-defence after Mr Greenwood attacked him when he went to buy books.

He also claimed the spreadsheet was compiled by a mystery man who he was afraid of, yet refused to name in court.

Danaher's defence was rejected by the jury, and the judge today ruled he had carried out "significant planning and premeditation" for his attack on Mr Greenwood.

The judge added: "It's clear from the timeline in this case you became almost obsessive about keeping up on famous celebrities."

Danaher remained impassive as the judge handed down the lengthy sentence.

Mr Greenwood's family issued a short statement after the hearing saying they were "pleased justice has been done for Adrian through this conviction".
