Martha and the Doctor land in New England. It’s almost Halloween and preparations are underway in the small town of Blackwood Falls. But as a green mist begins to cover the town, it’s clear that this will be no ordinary Halloween.

This was an enjoyable story and I really enjoyed Mark Morris writting. Plus Halloween was a great setting for the plot. However, the ‘monsters’ were weak: they seemed incredibly cartoonish. Overall this wasn’t the best of the series, but it was enjoyable enough.
