No political career in Northern Ireland has been as intriguing as Martin McGuinness's. Portrayed as a 'hawk' 'to Gerry Adams's 'dove', the former IRA leader was worshipped by republican grassroots, and loathed in equal measure by unionists.
But that was in the early days before Mr McGuinness's remarkable journey from revolutionary republican to someone who made peace with the British establishment.
Yesterday, prime ministers and presidents paid tribute to him. Footage of the former deputy first minister, statesmanlike shaking hands with the UK queen, flashed across our screens.
And yet there is another image that won't go away. The rain-soaked body of IRA informer, Frank Hegarty, on a lonely border road, bound and tied with masking tape over his eyes. His family claimed Mr McGuinness lured him out of hiding to be murdered.
Who could have foretold in those dark days of 1986 that the same man would later stand with a chief constable and a unionist leader to denounce other republicans continuing 'armed struggle' as "traitors to the island of Ireland"?
It was former Alliance deputy leader, Seamus Close, who perhaps most succinctly summarised Mr McGuinness's career yesterday when he described him as "the personification of war and peace".
There is no doubt that while his U-turn caused him to be despised by some traditional republicans, Mr McGuinness has been lionised by hundreds of thousands of nationalists.
During the Assembly election campaign, SDLP candidates reported an outpouring of sympathy for him on the doors with even their voters asking, 'How is Martin?'
At a healthy-looking 66, Mr McGuinness was preparing to go to China with Arlene Foster just three months ago. His death, so swiftly after falling sick, shows the fragility of human life from which no one is immune. Those gloating let only themselves down.
While some unionists continue to see him as nothing other than a widow- and orphan-maker, the attitude of others mellowed over the years. His compassion and concern for Ian Paisley and his family softened many hearts.
"He's not that bad. There are a lot worse than Martin McGuinness," I heard numerous ordinary unionists say after he fell ill. It wasn't always that way. There was horror in the Protestant community when he became education minister in 1999.
And yet as he visited schools up and down the country, he won over so many sceptics. He charmed Mr Paisley and previously hostile civil-servants. "Call me Martin!" he declared when other cabinet colleagues insisted on 'minister'.
His political opponents found him a straightforward operator. He told the Sinn Féin ard fheis that unionists should be "loved and cherished".
While Mr Adams was recorded talking about "breaking these b******s", nothing ever emerged to suggest any conflict between Mr McGuinness's public and private positions.
He had an easy, engaging manner and a great sense of humour. Colleagues said he would "talk to a stray dog". In one interview, he told me how he loved to cook dinner and when his daughters were teenagers they'd complained that he used too much garlic, causing problems when they met their boyfriends later. He relaxed by watching the very English 'Last of the Summer Wine' and 'Match of the Day'. "I've supported Manchester United since I was eight," he said. His greatest passion was fishing. "I like fishing alone in the dark. Some people are afraid of cows moving in fields or foxes beside the river but I love it," he said.
It wasn't surprising that he clicked instantly with the Rev Ian Paisley. Both were conservative family men who liked the simple things in life. "Although, I'm not quite as religious as Ian!" Mr McGuinness joked.
And yet old security force opponents, and many ex-IRA colleagues, agree that, beneath the easy charm, history showed a duplicitous and ruthless man. On the face of it, he was more honest about his past than Mr Adams, admitting he was an IRA member.
In 1973, appearing before Dublin's Special Criminal Court after being arrested by gardaí, he declared: "I'm a member of the Derry Brigade of the IRA and I'm very, very proud of it."
But that admission of a military role meant the detail of his involvement wasn't forensically examined. Frank Hegarty never haunted his political life the way Jean McConville did Mr Adams's.
And yet Rose Hegarty described Mr McGuinness on bended knee, promising her that her son would be safe if he returned from England. On the anniversary of Frank's death, Rose placed a newspaper notice denouncing "the Judas" who had betrayed him.
The man who condemned Massereene wasn't always so protective of human life. As Derry IRA commander, he claimed civilian casualties were inevitable.
Unlike other republicans at the coal-face of the war, Mr McGuinness emerged relatively unscathed. There were no lengthy jail sentences - he served only 14 months in prison in the Republic on two separate IRA membership charges - and no serious attempts on his life.
Tapes of his phone conversations with Frank Hegarty were never used by the security services. In 1993, detectives investigating Mr McGuinness's IRA links questioned the decision not to prosecute him despite three witnesses willing to give evidence.
Ex-British intelligence officer Ian Hurst - who previously used the pseudonym 'Martin Ingram' and who had outed senior IRA man Freddie Scappaticci as British agent 'Stakeknife' - claimed Mr McGuinness was a long-standing British agent. Mr McGuinness dismissed the allegation as "a load of hooey". But yet much is unexplained about the Sinn Féin leader's journey from guns to government. His dialogue with the intelligence services, over several decades, remains shrouded in secrecy.
He may well have penned a memoir to be published after his death. And perhaps other voices in both the republican and security world, which have until now been silent, will emerge to shed light on the fascinating life and times of Martin McGuinness.
Martin McGuinness was a man of impeccable manners. He was usually unfailingly polite and he was kind-hearted. This description may not fit the stereotype some would like to portray of a man who was active for a number of years at a high level in the IRA, but it accurately reflects the Martin McGuinness I knew very well for over two decades.
