The kids get lost and wind up in the spooky ghost town of Gold City. They check into the local ranch house hotel only to find that they are the only ones in this nice hotel–all the other guests are being scared away by the “Miner 49’er,” a miner who came to the city in 1849 and won’t leave until he finds the last vein of gold in the city’s old mine. The kids investigate the town, find a hidden entrance to the old mine, and unmask the “Miner 49’er”–and the real “gold” that the miner was digging up.
