An interview mentioning the enemies the Doctor and Susan will face as well as how and where Mr. Colfer became acquainted with the Doctor.
And a two-page extract.
Following from here.
“... the Doctor and Susan travel to Victorian times hot on the trail of a band of Soul Pirates who are harvesting human body parts to prolong their own lives.”
This may lead to the “big hand” of the title being a somewhat guignol pun.
Hmm, seems a bit derring-do for the First Doctor judging from that extract, but never mind.
