Prologue (Short Trips: The Centenarian).

Prose The aim of The Centenarian is to present the life of someone who constantly meets and aids the Doctor from his chronological or biographical perspective. This could be seen as a meditation on the nature of spin-off media, stories inserted between the gaps in the television continuity.  Here's a figure of huge importance in the Doctor's life that was previously hidden. The Prologue covers the birth of the protagonist, Edward Grainger, and is told from the point of view of a maid working in the Eaton Place-like setting, describing events and foreshadowing what's to come, a perspective at one remove from the position we're usually in during an adventure.  Since I'm focusing on the Eighth Doctor, I'll be diving straight into his main adventure within the anthology, but I'm intrigued enough to want to read the whole thing at some point.
Placement: The Doctor seems to be travelling alone so I'll arbitrarily put it between The Girl Who Never Was and Blood of the Daleks.
