Sweet Song of Death
by Stephen Kimmel
Dave, an old man on the verge of dying, partakes in a time travel experiment, hoping to
save his long-ago wife and young daughter from a car accident even though nobody has ever
managed to change past events before.
If our hypothesis is correct and the Corvini-Langstrum effect is a form of time
travel. . . then you may be able to change the circumstances
and prevent her death.
“Sweet Song of Death” by Stephen Kimmel, in Asimov’s Science Fiction, February 1983.
