She pays off her debt by smuggling pistols and builds a couture atelier for the protectorate's colonial elite. British intelligence later recruits her to open a salon in Madrid under the invented identity Arish Agoriuq, where she dresses the wives of Nazi officials and relays what she learns, then carries out a further mission in Lisbon.
Sira encodes intelligence in Morse code by drawing the dots and dashes as stitch marks along the edges of sewing patterns. The code passes inspection because a seamstress's patterns are expected clutter that no official thinks to read.

A couture salon collects information structurally.

Service workers whom the powerful treat as invisible end up holding the most candid view of elite networks.
Through Rosalinda Fox, the British lover of High Commissioner and later Foreign Minister Juan Luis Beigbeder, the novel shows an intimate relationship tilting a senior official of Franco's regime toward Britain and away from Germany.

This leverage is fragile, and Beigbeder's fall shows it vanishing when the relationship becomes a political liability.
