Overview
Step into the hidden underbelly of London with thirteen-year-old Agatha Oddlow, an aspiring detective with a scholarship to a prestigious school, a cottage tucked beside Hyde Park, and a mysterious key that unlocks secret passageways beneath the city. This stylish three-book paperback collection bundles together The Secret Key, Murder at the Museum and The Silver Serpent, delivering three fast-paced, clue-packed mysteries perfect for young readers who love puzzles, plots and a fearless heroine.

About the Books
In The Secret Key, Agatha finally gets a case worthy of her sleuthing skills when strange goings-on threaten the City of London. Armed with a scholarship to St Regis School and a secret key granting access to a hidden network beneath the streets, Agatha must work out who she can really trust. Murder at the Museum raises the stakes: Agatha is on the brink of becoming the youngest member of the secretive Gatekeepers' Guild, but first she must untangle a murder at the British Museum that the police seem to be missing entirely — a case involving a disused Tube station, a spectacular fireworks display, and thousands of tonnes of gold bullion hidden beneath the capital. Finally, in The Silver Serpent, an assistant at the National Gallery vanishes without a trace, and Agatha's investigation uncovers a conspiracy far larger than she ever imagined, taking her across some of London's most iconic landmarks. Told with pace and wit, each instalment stands alone while building a satisfying arc across the trilogy.
