Bonacieux rents rooms to d'Artagnan and profits from proximity to the queen's intrigue, but his courage collapses the moment danger touches him. His marriage to Constance is less a partnership than a leash he yanks whenever money or safety is at stake, and his willingness to sell anyone for a quiet life makes him useful to powerful men. He matters because his betrayals and panic keep exposing the conspiracy d'Artagnan is trying to protect.
