SCOTLAND'S most notorious gangster, Tam "The Licensee" McGraw, was found dead in his bed of a heart attack yesterday.
But a senior police insider said last night: "I didn't think he had a heart."
Another source added: "McGraw has been responsible for hurting and killing countless people.
"No one would have ever thought he would die of natural causes."
Gangland sources expect a spate of turf wars to break out as gangsters fight it out for control of McGraw's lucrative rackets.
An underworld insider said: "McGraw's death will open up a can of worms.
"People will be looking to lay a claim on his empire before the dust has been allowed to settle."
Few will shed tears for McGraw, a callous, tight-fisted villain who built his £30million empire on the misery caused by drugs.
One of his most bitter gangland enemies, former associate John Healy, threw a party to celebrate his death last night at a bar in Glasgow's east end.
McGraw, 55, complained to wife Margaret on Sunday night that he was not feeling well.
The chain-smoking crime lord was booked in for a check-up at a private hospital later yesterday.
But his wife walked into their bedroom at around 2.30pm and found him lying cold and lifeless.
Frantic Margaret called an ambulance when she could not wake her husband. Paramedics told her he was dead.
McGraw's body was taken to Glasgow Royal Infirmary.
Margaret was being comforted last night by McGraw's lieutenant, John "Joker" McCartney.
Associates of McGraw blamed his heavy smoking for his early death.
One underworld source said: "Tam must have smoked about 60 fags a day.
"He'd finish one fag and light another one straight away.
"He didn't really have a drink. When he did it was only lager and it was never a great deal.
"He never touched any drugs. The cigarettes were what he couldn't leave alone."
McGraw took over as Glasgow's Godfather after the death of crime lord Arthur Thompson, who also died in bed from a heart attack.
Despite his power, he was held in contempt by fellow-crooks as a police informer. He was known as The Licensee because his rivals believed he had a licence from the police to commit crimes.
Apart from a drink-driving charge in 2005, McGraw had not been convicted of a single offence in 20 years.
He was acquitted of the attempted murder of a police officer in 1978. And he walked free on a not proven verdict in 1988 after being charged with smuggling cannabis from Spain in a youth football team's minibus.
For all McGraw's reputation as a "grass", cops hated him just as much as his gangland enemies.
One high-level police source said: "I'm shocked to learn that he died of a heart attack. I've known him for many years and I didn't think he had a heart.
"Take it from me, many police officers will be raising a glass and toasting his death this evening."
McGraw ruled by fear but was derided by enemies as a coward.
He was terrified of assassination, and his plush £400,000 home in Mount Vernon, Glasgow, was heavily fortified against attack.
But despite his reputation, one local resident described him as a great neighbour.
The man said: "I never had any problems with him and he would always stop and chat with me."
McGraw began his crime career as a small-time thief in the east end. He had few friends and was not known as a fighter, but his ruthless-ness and love of money soon drove him up the criminal ladder.
He became a leading member of the Barlanark Team, a notorious gang of armed robbers.
But his empire really began to grow when he moved into the drugs trade. He started out by peddling cannabis, then moved into heroin and cocaine.
McGraw played a leading role in the notorious Ice Cream Wars, where rival gangs battled one another for the right to sell heroin from ice cream vans.
Scotland was horrified in 1984 when the wars claimed the lives of six members of one family, the Doyles, who perished in an arson attack on their home.
TC Campbell, a former Barlanark Team colleague of McGraw, and small-time crook Joe Steele were jailed for life for the murders. But the pair had their convictions quashed in 2004. Campbell later blamed McGraw for the attack.
In 2002, McGraw attacked Campbell, who was on bail pending an appeal for the Doyle murders, with a golf club in the street.
Although McGraw led a charmed life himself, three of his most trusted associates were not so lucky.
Trevor Lawson was mowed down and killed by a car in revenge for the deaths of Bobby Glover and Joe Hanlon, who had themselves been killed in retaliation for the murder of Arthur Thompson's son Arthur jnr.
Gordon Ross was stabbed to death outside his local, The Shieling Bar, after creating havoc in the pubs and clubs of the east end.
Billy McPhee became McGraw's No2 after the deaths of Lawson and Ross, but he too met a grisly end. He was stabbed 27 times while watching a rugby international in a pub.
As his empire grew, McGraw branched out into legitimate business, including pubs, private hire taxis and property.
But drugs remained his biggest earner. And as the trade became more violent, he felt more under pressure than ever before.
In 2004, he survived a gun attack at the Royal Oak pub in Nitshill by diving under a pool table as the hitman opened fire.
Joker McCartney and another McGraw associate, Craig Devlin, were wounded. McGraw bundled them into his car and drove them to casualty, commandeering a police escort on the way.
The next year, McGraw, again armed with a golf club, attacked another of his many enemies, Paul Ferris.
Ferris, a former enforcer for Arthur Thompson, had been a close ally of McGraw. But the pair fell out bitterly as they struggled for control of the Thompson empire.
McGraw's house was deserted for several hours after his death. People driving past slowed down to get a look at the Godfather's lair.
At around 6.30pm, a Mercedes and two BMWs drew up at the house and about a dozen people made their way inside. A man in his 20s shouted obscenities at our reporter when he asked the group to comment.
