Time travel has many dangerous caveats.
One can never change the past,
But one can affect the future.
Ask one Robert Boller what he thinks about all that.
He traveled back in time to save his grandmother's life.
One little screw-up and now his grandmother now knows him as her hero.
It can be pretty crazy to have...
One Foot In Yesterday.
ONE FOOT IN YESTERDAY (AN EXCERPT)
...Robert's time machine transported him a horrified Boston of 1962... in order to prevent his grandmother's death.
Robert's purpose for traveling back in time from 2015 was to kill the man who enacted a grotesque murder spree.
That despicable man is one Albert Desalvo, a.k.a the Boston Strangler, who needs to die in retrospect.
Robert saved his grandmother, killed the impending serial murderer... and now has to fend off his grateful grandmother's advances.
