El caso del ladrón fantasma (Los cazamisterios, 2)

When their parents aren't home, strange things always happen to Ulysses, Nora, and Bruno Misterio. Very, very strange things. Luckily, they have Bobo, a talking dog whose nose squeaks when he finds a clue! The Haunted Bakery would be the best in town… if it had any cakes. Every night, the sweets in its window disappear without a trace. Yum, yum! Could its famous ghost be eating them?
