So 'Silk' is no more, no 4th series according to the Telegraph
It's been cancelled.
Gutted.
We'll never know where our Martha went that night.
It did have some closure though. Clive becomes head honcho (and with his flawed background behavior, that cannot end well). Billy's expert old-school clerking is a thing of the past, as he is now. His collapse at the end could only end up in hospital or transferred to a hospice.
And Shoe Lane has lost its dedicate hallmark as a chambers that defends the downtrodden, by switching to prosecution.
So there is some closure.
But still! No more "Silk." Sigh. Say it ain't so.
