Valley of the Eagles

The setting is Stockholm, Sweden, "this year". Dr Nils Ahlen, working at the "Institute of Technical Research", is about to leave his home to give a talk at Uppsala University on his new invention and he discusses arrangements for his absence with his assistant, Sven Nystrom. Nystrom intends to work from home, but Ahlen shows him where he has hidden the key to his laboratory "just in case". While they are talking, Ahlen's wife, Helga, complains that the couple will miss a dinner engagement with friends. Ahlen tells her she could go on her own and Helga replies that she could.
