Despite being fairly unfamiliar with the 7th Doctor or his companions, this was still a fun read, a nice slow paced mystery that came together logically at the end. Unlike the adventures I've read of the 10th and 11th Doctors, which were self contained stories, this book is really part of series that you need to have read previous books to get the full geist of the characters. 3💥💥💥 1/2 out of 5.
