Finally, a story that something fully of the Paternoster Gang. I cannot see how either Jago and Litefoot or Doctor Who proper would fit this better.

It's also a cracker. I've done this one before, but at that time I zoned out at the end, which is a shame: it starts good, gets better and ends best. Also a very good entry for carnacki fans, for those who have done the 7th Doctor boxset.

I can't say much due to spoilers; this one is worth doing, so I won't spoil it.
