Something is cooking...

...They have not told the whole story and if he knows, he is not allowed to tell.

Actually, they (the investigative branch) has not divulge the Truth!
There is much more to this Drama than being told.
He found or stole that box of perfume, so, with that kept inmind, that Nerve Agent was intended for him or her.
If, his story is the truth.

The whole story hasn't been put to script yet, that's why!!

Mercedes with Romanian number plates was seen near poisoned Russian spy Sergei Skripal
several times before Novichok nerve agent attack.

*Police are scouring CCTV footage from a garage in Salisbury where car was seen
*Resident claims it was seen four times in the week before Skripals were poisoned
*One of the four occupants of the dark-coloured car was a woman, witness said

'A Mercedes with Romanian number plates was seen near former spy Sergei Skripal's home several times
in the week before he was poisoned with a nerve agent, it has emerged.
According to witnesses, one of the four occupants of the dark-coloured car was a woman. 

Police hunting the would-be assassins who poisoned Mr Skripal and his daughter Yulia in March have been
scouring CCTV footage from a Shell garage in Salisbury where the Mercedes was seen.

As it emerged the huge investigation –codenamed Operation Fairline –has already cost £7.5 million, the
detective leading the hunt faced questions about the sightings at a public meeting. 
But Detective Chief Superintendent Kath Barnes said: 'I can't comment on any individual report like that.'

A woman told the meeting that the Mercedes was seen 'four times in one week prior to the week it
[the Skripals attack] happened'. She added: 'One time was in the Wilton Road garage.
The car had Romanian number plates and there were four people in the car. There's CCTV.
He paid by credit card.

'They were seen four times around Salisbury early morning, like 6.30 in the morning, also late at night between
11 and 12... you wonder whether they were doing some kind of reconnaissance.
'An Eastern European car, travelling with four people, at that time, on several occasions, close to where the Skripals
live, is surely relevant.'

Det Chief Supt Barnes said: 'When we catch the people responsible and get them into court and the evidence is
being heard, that's when the full story will emerge. I do not want to jeopardise any opportunity of that end result.'

Police believe the Novichok nerve agent was smeared on the door handle of Mr Skripal's home over the weekend
of March 3 and 4. Mr Skripal, 66, and Yulia, 33, are recovering at a secret location.

The meeting was held in Amesbury where Charlie Rowley, 45, and Dawn Sturgess, 44, were struck down last month
after finding and opening a branded, sealed perfume bottle containing Novichok.
Miss Sturgess, whose funeral will be held in Salisbury tomorrow, suffered a fatal dose after spraying herself with the
'oily' substance...'

I agree with Guohua, this unopened perfume box was probably 'acquired' by questionable means and the 'innocent victim' card
becomes sullied. I suspect Rowley will fade away from this tale and another sinister 'baddie' will be brought onto the stage.
