The Doctor, Amelia Ducat and others in “The Seeds of Doom”

We're trying to trace the owner.

Isn't it [her painting] yours?

No. We found it in a car boot

A car boot?

A Daimler car boot

The car is immaterial.

Sarah

The driver wasn't. He tried to kill us.

Can you remember who bought this particular painting?

Well, nobody. I haven't finished it yet.

Sarah

No, hang about, not that one. This one, Miss Ducat.

Common snakes-head fritillary.

Oh, that one. Oh, dear me. It was a long time ago. Now what was his name? Something like face? Mace? Lace?

Sarah

Pace?

Base?

That's right. Chase! Of course. Harrison Chase the millionaire. Good lord. He never paid me!
