Grant Munro's happy marriage takes a dark turn when his wife, Effie, begins acting strangely—sneaking out at odd hours, hiding letters, and pleading with him to trust her without explanation. His suspicions deepen when he discovers her visiting a nearby cottage, where a mysterious figure with a ghastly yellow face stares back at him from an upstairs window. Desperate for answers, Munro seeks the help of Sherlock Holmes and Dr. Watson.
As Holmes investigates, he believes he has unraveled the truth behind Effie's secret. But when the final revelation comes, even the great detective is forced to admit his logic has failed him. What seemed like a case of deception and betrayal turns into a deeply moving story of love, sacrifice, and societal prejudice.
A unique and thought-provoking entry in The Memoirs of Sherlock Holmes, The Yellow Face challenges both detective and reader alike, proving that not all mysteries are solved by cold deduction alone.
