Ghosthunters!

"Once there was a family. Their name was Baker. They had many children. Twelve of them. The Baker's Dozen. The move to the spacious old Wharton Mansion seems like a dream come true. But the dream quickly turns into a nightmare. On the very first night eerie noises wake Tikva. She soon stumbles on an intruder right in their own basement! But her family doesn't believe a word of her story...or understand a series of other puzzling incidents. Could the old house actually be haunted? A wild baseball shatters a window, bringing Chezky face-to-face with Grouchy Mr. Schwartz and his terrifying dog. To pay for the damage, Chezky faces a long term of hard labor. In desperation, he hits upon a different way to raise money, one that leads him and his sisters into more trouble and more danger than any of them could have foreseen."--Amazon.com.
