HBO Max introduces a fresh interpretation of the legendary detective with Sherlock & Daughter, a mystery thriller starring David Thewlis as Sherlock Holmes. Set in 1896, the series follows an older Holmes who finds himself unable to investigate a dangerous conspiracy without putting his closest friends at risk. His situation changes when Amelia Rojas, played by Blu Hunt, arrives in England following the mysterious murder of her mother. Amelia believes that Sherlock Holmes may be her missing father, creating an unexpected connection between the two characters. Despite their different backgrounds and personalities, they must work together to uncover the truth behind her mother's death and investigate a powerful criminal organization. Their investigation also brings them into contact with Professor James Moriarty, portrayed by Dougray Scott, who becomes an important part of the unfolding mystery. The cast also includes Fiona Glascott, Seán Duggan and Joe Klocek. Created by Brendan Foley and led by showrunner James Duff, the eight-episode series combines Victorian detective storytelling, family secrets, suspense and international conspiracy.
Following its American debut in 2025, Sherlock & Daughter arrived on HBO Max in the UK and Ireland on November 5, 2026, with episodes released weekly through December 24.
