Anthony Cade—Hiram Fish

Anthony Cade—Hiram Fish is a relationship forged through mistaken identity and converted into cooperation. Hiram Fish first follows Cade under the impression that he is King Victor; once the deception is understood, the two coordinate their actions against the impostors and the diamond plot.

From mistaken suspicion to cooperation

Cade later explains that he went to Dover and Fish followed, believing Cade to be King Victor. At the Dover hideout they encountered a mysterious prisoner. Hearing the stranger’s account revealed a familiar pattern: the real man had been kidnapped, while a false one had taken his place. The encounter gave Cade and Fish the information needed to recognize the larger impersonation scheme.

Their cooperation is practical rather than founded on an established personal history. Fish’s pursuit brings him to the same discovery as Cade, and the two act together once they understand what has happened. At Chimneys, Cade says Fish had already reached the same conclusion about the diamond’s hiding place: Count Stylptitch’s device represented a rose, directing them to the rose garden and the bright red Richmond roses.

The trap at Chimneys

The pair also coordinate their surveillance. Cade invents a story that the diamond is hidden among the library books to draw Mademoiselle Brun into a search. Fish watches the terrace and whistles when the moment is right. The false clue gives them a way to observe the suspected accomplice without immediately exposing their real discovery.

At the Dover house, Cade and Fish establish martial law and prevent the Comrades of the Red Hand from communicating with the false M. Lemoine. The impostor receives an order for them to leave, and word reaches him that they have complied. Believing that the obstruction has been removed, he proceeds with his plans to denounce Cade. Their control of communication thus helps sustain the deception while the investigation advances.

What the partnership reveals

Cade’s account presents Fish as both an investigator capable of recognizing the impersonation and a partner in a coordinated operation. Their shared work links the discovery at Dover to the later surveillance at Chimneys: first they learn that a real person has been displaced by a false one, then they use observation and a planted clue to frustrate the impostors’ attempt to recover the diamond.

The relationship’s defining feature is its reversal. Fish begins by pursuing Cade as a suspected King Victor; by the time Cade explains the case, they have joined forces against the false M. Lemoine and the people assisting him. The shift turns an encounter produced by mistaken identity into an investigative alliance, with Fish’s watch on the terrace and their joint restrictions at Dover helping expose the scheme.
