John Brown's *Marjorie Fleming: A Sketch* is a brief yet memorable Victorian biographical portrait of the precocious Scottish child-writer Marjorie Fleming, whose journals, letters, and verses reveal a mind at once playful, morally earnest, and startlingly intelligent. Brown writes with tenderness and literary tact, shaping fragmentary family materials into an elegiac meditation on childhood, genius, and early death. The book belongs to the nineteenth-century tradition of affectionate memorial sketching, yet it stands apart for its delicate balance of sentiment and irony, preserving Marjorie's lively voice rather than merely idealizing her. Brown, the distinguished Scottish physician and man of letters best known for *Rab and His Friends*, brought to his writing both clinical attentiveness and humane sympathy. Deeply rooted in Edinburgh's intellectual and religious culture, he was drawn to figures whose inner life disclosed unusual moral and emotional depth. His interest in Marjorie Fleming reflects his broader concern with memory, mortality, and the fleeting brilliance of individual character. This volume is especially recommended to readers of Victorian literature, Scottish letters, and life writing. It offers not only an enchanting portrait of an extraordinary child but also a moving reflection on how biography can rescue a voice from oblivion with grace, restraint, and profound affection.
