No Strings Attached

No Strings Attached is a science fiction short story by American author Lester del Ray, first published in 1954. 

Poor Henry was an unhappy husband whose wife had a habit of using bad clichès.

Alféar was a genii who was, quite like most humans, a creature of habit.

Their murder compact was absolutely perfect, with—no strings attached.

No Strings Attached was first published in IF Worlds of Science Fiction June 1954.
