The First Doctor #14

'The Message of Mystery' (1964) from The Dalek Book.

A very odd little story with no adherence to the chronology of events but the stark difference in the Daleks' behaviour is highly interesting considering the time period. They'd only been in one story so far and weren't so deeply set on being evil incarnate, so seeing them have respect for Susan and even grow fond of her is a strange but unique thing to see.
