# We Achieve Our Double Aim explained — The Riddle of the Sands

> Chapter companion for The Riddle of the Sands by Erskine Childers.

## What happens

Carruthers escapes from the stranded tug and reunites with Davies aboard the Dulcibella. They confront Dollmann at his villa, accusing him of treason, but Dollmann claims to be in British service. After a tense standoff, they force Dollmann and Clara to accompany them on a desperate sail to Holland. During the voyage, Dollmann (X⸺) disappears overboard, and Carruthers and Davies eventually reach England.

## Key lines

> Full speed on a falling tide! They were pinned there for five hours sure.

The tug was stuck fast until the tide rose again, giving Carruthers a five-hour head start.

_Carruthers exploits the tidal conditions to escape._

> I pulled furiously up the harbour past a sleeping ferry-steamer and—praise Heaven!—came on her warped alongside the jetty.

Carruthers rows desperately back to Norderney and finds the Dulcibella safely moored.

_Reunion with Davies is imminent._

> A traitor in German service

Davies accuses Dollmann of being a double agent working against Germany.

_Central accusation of the confrontation._

> I'm in British service! You're wrecking the work of years—and on the very threshold of success.

Dollmann claims he is actually a British spy, and their interference is ruining his long-term mission.

_Dollmann's counter-claim creates doubt._

> He must have slipped over quietly … He had an ulster and big boots on.

Dollmann likely jumped overboard deliberately, weighted down by his heavy clothing.

_Dollmann's fate is left ambiguous but suggests suicide or escape._
