Simplest Solution

Imagine if Ray Winstone‘s Gal Dove had played his cards a different way. A much simpler way. Instead of sweating bricks when told that crazy Don Logan was on his way down to his Spanish hillside villa to convince Gal to “do the job,” what if Gal had simply said “okay, fine, I’ll do it, but this is it, Don.

“I mean I quit the life and I moved to sunny Spain for a reason, right…I’ll do this for old times’ sake or to get you off my bloody fuckin’ back or whatever, but this is not the start of something…right, Don? One more time and that’s all. Give me your word and I’m in.”

And then Gal would fly to London, put on his Speedo and do the job with the rest of those fat old blokes, and when it was over he’d take his cut and head back to Spain and that would be that. No blood, no trauma, no paranoia, no dead Don Logan, no Teddy Bass giving him death-ray looks…everything would’ve been fine. Why didn’t Gal just do the job?’
