Who Sergeant Cuff is
Sergeant Cuff arrives at the Verinder house after Franklin Blake sends to London for help with the missing diamond. He is thin, grey and quiet, with a face that resembles a tired scholar's.
He is also a devoted grower of roses, looking at gardens as eagerly as crime scenes. This interest leaves the loyal house steward, Gabriel Betteredge, partly charmed and partly annoyed.
What Sergeant Cuff wants
Cuff seeks answers by examining the paint smear, checking accounts of laundry and listening closely to the household. He believes useful truths often lie in details others overlook and behaviour people show when they think nobody watches.
Rosanna Spearman's secretive movements draw his attention, while Rachel Verinder's stubborn silence suggests that she is hiding something. He waits and observes rather than raising his voice or boasting about his abilities.
Sergeant Cuff and the others in the story
Cuff's reasoning brings him into conflict with Betteredge, who trusts the family and wants to defend Rosanna. Their disagreements set the steward's affection and loyalty beside the detective's cooler attention to evidence.
He also contrasts with Superintendent Seegrave, whose rough questioning leaves the servants feeling insulted and suspected. Cuff's quieter methods turn attention toward small clues and the household's guarded behaviour.
