The scriptwriter Tony Owen just wrote this succinct (and flattering) description of the novel (25/07/2014, via email):

I just wanted to let you know how much I enjoyed reading Snug. I found it original, clever, imaginative and affecting. At times I could hardly put the book down, so keen was I to find out what happened and I loved the twist at the end when Lucy turns out to be a chip off her father’s block.
