But then hero turned villain. Fergus Watts vanished and soon after it was discovered he'd gone over to FARC, purely for the money.

'It's true,' said Danny as they scrolled on to another page. 'It's exactly like the guy at my RCB said, he betrayed the Regiment and his country.'

A long in-depth article from a correspondent in Colombia said that the manufacture and export of cocaine to the USA and Europe was a multi-billion-dollar business, and that in selling his skills and taking the FARC 'blood money', Watts shared the responsibility for the deaths of thousands of young drug users.

'He's no better than a murderer,' said Danny angrily. 'A mass murderer.'

The newspaper stories revealed that the traitor had eventually been captured after a gun battle between his small band of FARC guerrillas and Colombian soldiers. Watts had taken a bullet in the thigh during the fighting and was later tried and thrown into a Colombian prison to rot.

After the trial and jail sentence, the name Fergus Watts disappeared from the newspapers for over four years, but then there was a dramatic return to the headlines:

SAS TRAITOR MASTERMINDS

MASS PRISON BREAKOUT

Since the breakout Watts had never been seen, or heard of, again.

'He's here,' said Danny. 'He's in England.'

'You can't know that,' said Elena. 'He might still be in Colombia – he might even be dead.'

'Yeah? So who was it made the enquiry about me? It had to be him, there's no one else, and I'm gonna find him. I'll phone the SAS to start with and see what they can tell me.'

'Danny, it's a secret regiment. What you gonna do, ring one-one-eight and ask to be put through?'

Danny was in no mood to be corrected. 'Yeah, all right,' he snapped, 'it was a stupid idea. So what do I do?'
