Publisher's summary
Nora Wicker is forgetful. Not big things - not yet, anyway. She remembers her address and where the shops are. She remembers people when they come to visit, no matter how rare that is.

But she doesn't remember where the bush with the red leaves in her garden came from - and she definitely doesn't remember asking for a house call from the Eleventh Doctor.
