Captivating, haunting and an eerie setting that grabs your attention from start to finish. The way this story is told makes the unfolding of the mystery much more interesting.

Plus the final plot twist is as dark as Doctor Who can get in my opinion.

When it comes to the Fifth Doctor Range I'm usually asleep half way through and I have to rewind (except for the excellent Spare Parts) but this story was amazing, hope the quality keeps being this high (probably not but oh well)
