It’s been 56 years since the United Intelligence Taskforce (as they became known) first appeared in the series, to help the Doctor with some of the heavy lifting involved in repelling attacks from outer space – and other assorted catastrophes!

Authors Mike Tucker and Steve Cole have imagined a variety of sources that build to give a comprehensive account of the alien invasions of Earth. This lavishly illustrated volume is full of news reports and documents that cover the various incursions seen on TV over the years. The Doctor is also on hand to fill in some of the gaps in their knowledge… and the Time Window, seen in this year’s season finale, gives them a vague glimpse into the future!

You can grab a copy of the book from all the usual retailers (RRP £35), but we have FIVE copies on offer. Just send us the answer to the following question.
