A Night in Terror Tower by R. L. Stein

Sue and her brother Eddie are visiting London when they run into a little problem. They can't find their tour group. Still, there's no reason to panic. No way their tour guide would just leave them. All alone. In a gloomy old prison tower. No way they'd get locked inside. After dark. With those eerie sounds. And a strange dark figure who wants them ... dead! A favourite Goosebumps, now with all-new bonus features including author secrets, fear facts and haunting games!
