# XXI explained — The Moonstone

> Chapter companion for The Moonstone by Wilkie Collins.

## What happens

Sergeant Cuff presents his case against Rachel Verinder and Rosanna Spearman to Lady Verinder and Betteredge, proposing to surveil Rachel and introduce a spy into the household. Lady Verinder rejects his plan but accepts his alternative: to shock Rachel into confessing by revealing Rosanna's death. She insists on conducting the test herself and drives to Frizinghall.

## Key lines

> I want to give her a great shock suddenly, under circumstances that will touch her to the quick. In plain English, I want to tell Miss Verinder, without a word of warning, of Rosanna’s death⁠—on the chance that her own better feelings will hurry her into making a clean breast of it.

Cuff proposes to shock Rachel by unexpectedly informing her of Rosanna's death, hoping her conscience will compel her to confess.

_Cuff's psychological strategy to elicit a confession._

> My mistress astonished me beyond all power of expression. She answered him on the instant: 'Yes; I do.'

Lady Verinder immediately agrees to Cuff's bold experiment, surprising Betteredge.

_Lady Verinder's decisive acceptance of the risky plan._

> I claim the right, as her mother, of putting her to the test myself. You will remain here, if you please; and I will go to Frizinghall.

Lady Verinder insists on personally confronting Rachel, asserting her maternal authority over the investigation.

_Lady Verinder takes control of the experiment._
