Mr. Grimwig
Mr. Grimwig is introduced as a stout, lame old gentleman with a thick stick, a blue coat, striped waistcoat, nankeen breeches and gaiters, and a broad-brimmed white hat. His most distinctive verbal tic is the repeated offer to "eat my head" if his predictions prove false—a promise he backs by striking his stick on the ground. He has a manner of screwing his head on one side when he speaks and looking out of the corners of his eyes, which irresistibly reminds the beholder of a parrot. His first appearance at Mr. Brownlow's house is marked by his discovery of a piece of orange-peel on the staircase, which he immediately declares will be his death, and he proceeds to denounce the surgeon's boy whom he believes responsible. Despite his gruff exterior, Mr. Brownlow assures Oliver that Grimwig is "a worthy creature at bottom."
Skepticism and the Test of Oliver's Character
From the moment he meets Oliver, Grimwig adopts a posture of aggressive disbelief. When Mr. Brownlow expresses his intention to hear Oliver's full history the next morning, Grimwig whispers that the boy will not come, declaring, "He is deceiving you, my good friend." Mr. Brownlow retorts, "I'll answer for that boy's truth with my life!" and Grimwig counters, "And I for his falsehood with my head!" This wager sets the stage for a deliberate test: Mr. Brownlow sends Oliver to return books and pay a debt, carrying a five-pound note. Grimwig then predicts with absolute certainty that the boy, now possessing new clothes, valuable books, and money, will join his old thief companions and never return. He admits to himself that he "really did most earnestly and strongly hope at that moment, that Oliver Twist might not come back," so that his judgment might be vindicated. When Oliver is recaptured by Nancy and Sikes and fails to return, Grimwig's skepticism appears confirmed, and he later gloats, "I knew it all along. Why didn't you take my advise in the beginning?"
Role in the Revelation of Oliver's Identity
Grimwig's role shifts from skeptic to active participant once the truth begins to emerge. When Rose Maylie visits Mr. Brownlow to report Oliver's reappearance, Grimwig is present, and his characteristic disbelief is momentarily suspended by the emotional force of the reunion. He performs a comic dance on his chair, then rises and kisses Rose without preface, declaring, "Don't be afraid. I'm old enough to be your grandfather. You're a sweet girl. I like you." Mr. Brownlow later proposes calling in Grimwig's aid, describing him as "a strange creature, but a shrewd one," and noting that he was "bred a lawyer, and quitted the Bar in disgust because he had only one brief and a motion of course, in twenty years." Grimwig is accordingly added to the committee investigating Oliver's parentage. He takes charge of producing the Bumbles as witnesses, disappearing "with great alacrity" and returning with the reluctant couple, and later leading in the two palsied old women who confirm the pawnbroker transaction. His legal training makes him an effective agent in extracting the truth.
Thematic Significance and Final Portrait
Grimwig embodies the novel's tension between cynical worldly wisdom and the redemptive power of faith in human goodness. His repeated predictions of Oliver's villainy are proven wrong by the boy's actual character, yet Grimwig himself is gradually won over. In the final chapter, Mr. Brownlow rallies him on his old prophecy, reminding him of the night they sat with the watch between them waiting for Oliver's return. Grimwig "contends that he was right in the main, and, in proof thereof, remarks that Oliver did not come back after all; which always calls forth a laugh on his side, and increases his good humour." He becomes a regular visitor to the country parsonage, where he plants, fishes, and carpenters with great ardour, always insisting his mode is the right one. On Sundays he criticises the young clergyman's sermon to his face, but privately informs Mr. Losberne that he considers it excellent. His stubbornness becomes a source of affectionate comedy rather than genuine opposition, and he is integrated into the happy society that concludes the novel.
