The House on Hackman's Hill — Joan Lowery Nixon

A NIGHT OF TERROR
As Jeff and Debbie make their way to the old Hackman mansion, snowflakes start to fall. They come to the house on Hackman's Hill to look for a stolen Egyptian mummy that old Mr. Karsten has told them about -- and for which they could get a ten-thousand-dollar reward!

They have heard Mr. Karsten's horrifying tale of accidents and disappearances that surround the old mansion. But they don't listen to his warning -- "Stay away from that place!" And as the snow gets thicker and thicker, and the drifts grow higher and higher, Debbie and Jeff find themselves trapped in the house with a mummy that lives!
