(papers thud) - This woman, Irena Lewandowska, you know her?

- [Kasia] No.

- She works at the Avro factory, you know it?

It's where they're building the new bomber, the Lancaster.

For now, just watch her, follow her.

Anything suspicious, any signs of activity, report back.

She walks it every day at 10 o'clock, then again at five o'clock.

We'll get you a dog for cover.

(footsteps tapping) - Miss Tomaszeski?

- Yes.

- May I ask, do you know what I mean by a bland smile?

- A bland, I don't know that word.

- Flavorless, or, in the case of smiles, meaningless.

- Like this?

- Ah.

You yourself know that Robina is the most acute of women.

Keep hold of yourself.

I feel she knows something is afoot.

Oh, I know you're an honest woman and this sort of thing doesn't sit well with you.

But try to think of it as an essential skill, rather than a defect of character.
