Rejected title Number 5 - The Big Slipper. (We didn't say these were all great titles. That's largely why they're the rejects. Bear with us, better to come)
We've already seen Brighton Sock, The 39 Insteps, Good Smellas, Lock Sock and Two Smoking Barrels and Chinatoon. And you'll find dozens of fan suggestions here from Facebook, one of which hits the nail on the head, but we're not telling you which.
And how's this for a stellar suggestion? Only Britain's top crime writer suggesting a title for us! And here are some more titles that are close but no cigar:
@dinogoldie Prime Suspender, A snitch in crime saves time, Cheesy blinders, Wollandar, Dixons of Sock Green?
@LordSiBorg The Sockford Files
@reesmf A Sock in Scarlet, Socks and Crosses, A Sock in the Night, The Maltese Sock, Enter The Sock (and all the other Saint titles)
@crgn M&S Confidential?
