Whatever your view of him, no one can dispute that Kieren Fallon's lengthy absence from British Flat racing has left a gaping hole, one that nobody has been able to fill.
Quite possibly Flat racing's most exciting jockey ever is back where he belongs
So his return after serving an 18-month ban for a recreational drugs offence can be rated among the most significant racing events of the year.
Brilliant positioning and determination during a race, Herculean strength in the saddle and an acute understanding of his mounts brought Fallon six championships, 15 Classic races and the adoration of his fans.
However, there's also been another, darker side to 'King Kieren', one that makes some uneasy about the almost ecstatic levels of welcome for his comeback, which will be at Lingfield on Friday.
There was the furious hauling of another rider from his mount after a race at Beverley, regular clashes with authority, and an earlier a six-month drugs suspension.
But they were nothing like the events of September 2004 to July 2006, when Fallon was dramatically arrested, questioned, bailed and finally charged by detectives investigating allegations of race-fixing.
As soon as those charges were brought, the authorities in Britain suspended Fallon's riding licence pending any trial, and that's why he hasn't ridden in Britain for over three years.
Regulators in Ireland and France refused to recognise the suspension so he was permitted to line up on Dylan Thomas in the Prix de l'Arc de Triomphe of 2007, a race he won despite the pressure of an appointment in the dock at the Old Bailey next day.
Two months later, the trial collapsed, with all six defendants walking away free.
Owners and trainers have been queuing up for his services while punters prepare to get back into the habit of supporting his every mount
But seasoned observers of the topsy-turvy world inhabited by Kieren Fallon know of his almost uncanny ability to cancel out a positive with a negative.
And such a situation surfaced on the same day with news of the failed test for a Class A drug in France.
It being a second offence, an 18-month global ban was imposed.
Many who saw his drained demeanour outside the Old Bailey wondered if that might be the final nail in the racing coffin of one of the sport's all-time great talents.
But, once again, Fallon has silenced the critics, returning positively bright-eyed and bushy-tailed, the fittest he's ever been, his troubles, seemingly, behind him.
The significance of all this for Flat racing cannot be underestimated.
Sea The Stars' Group One rampage, taking in the 2000 Guineas, the Epsom Derby and the Eclipse and International Stakes, has been the equine highlight of the season.
Fallon is fitter than ever after his enforced lay-off
But in the 'People Stakes', away from the rightly-lauded Sea The Stars team, things have been a touch on the quiet side - now however, Fallon is back.
And his rivalry with the currently unchallenged champion jockey Ryan Moore is likely to make up a priceless "narrative" for 2010, with Fallon aspiring to a seventh championship.
Absence has indeed made many hearts grow fonder. Owners and trainers have been queuing up for his services while punters prepare to get back into the habit of supporting his every mount.
The regulating British Horseracing Authority (BHA), which brought in the police and imposed the suspension when charges were brought, is not commenting on his return.
But there has been a big element of kissing and making up, with officials at the authority apparently telling Fallon they want to see him back again, and the jockey assuring them he will not be "reckless" with the Rules of Racing in future.
Those that are dubious should give him another chance; there is no reason not to be glad about his return.
He has served his sentence for the drugs offence, and having reviewed all the evidence that led police to the Old Bailey, the BHA has decided not to proceed.
Quite possibly Flat racing's most exciting jockey ever is back where he belongs.
