They're coming off. It's pretty much pitch black at Lord's and the floodlights have taken over completely.
That'll probably be that for day four with Somerset leading by 191.
It sets up the final day very nicely!

Vic Marks
Ex-England spinner on BBC Radio 5 live Sports ExtraAlastair Cook has not missed anything in this match.
It was a fairly regulation catch but, it still had to be taken and he's taken a few crucial ones this evening.

Somerset are definitely giving themselves something to bowl at tomorrow now.
A couple to Steven Davies off Simon Harmer's 26th over as he moves to 18.

'Never a nice moment as a 12th man'published at 17:08 British Summer Time 26 September 2020
Varun Chopra
Essex batsman on BBC 5 Radio Live Sports ExtraI'm a bit surprised Ben has put that one down, he's taken a couple of really difficult catches like that in a T20 Blast match earlier this season, probably harder.
It's never a nice moment as a 12th man to come and shell a catch like that, especially when the game is in the balance a bit.
It just replays in your mind for a period and you feel bad for your team-mates.

Somerset 205-6
Oh no, that's a bad drop by substitute fielder Ben Allison.
Craig Overton hooks Sam Cook straight to him at fine leg but he shells the chance. In and out.
