detective who's only eleven years old.
When Poppy Hudson, the sharp-eyed niece of the world's greatest consulting detective, is sent to stay at 221B Baker Street for the summer, she expects boredom. Instead, she finds secret codes, hidden clues, Victorian London fog rolling down cobbled streets, and a mystery Sherlock Holmes himself hasn't solved.
Teaming up with Ollie, a streetwise member of the Baker Street Irregulars, Poppy must learn the art of deduction, disguise, and observation to catch a thief who's been stealing precious oddities from every corner of the city - a stolen jewel, a vanished violin, a coded letter, and a kidnapped prize-winning goose.
Packed with puzzles to solve alongside Poppy, secret detective notebooks, red herrings, narrow escapes, and a thrilling final confrontation in the shadow of Big Ben, this is a mystery adventure for every young reader who's ever wanted to be a detective.
Elementary, my dear reader - the game is afoot
