## Snapshot

An aging aristocrat whose urgent, breathless errand to a barrister's rooms conceals a guilt he has carried for decades.

## Who they are

The Count de Commarin moves through Paris with the authority of old nobility, yet his composure cracks the moment he climbs the stairs toward Madame Gerdy's apartment. His name alone silences servants and startles strangers, but it also draws a flash of hatred from an old soldier in the room. His buried connection to the Lerouge affair makes him the quiet engine of the novel's central mystery.
