The day time stopped moving by Bradner Buckner

A nice short story, about ten pages long. It start with a suicide: Dave responded to the difficulties of life by wasting himself; instead of looking for a solution hoping for better days he started drinking, a lot, and losing money betting on horses. His wife Helen could not stand this situation any more and after having many times threatened to leave, she finally does. He comes home twelve hours late and totally drunk and upon seeing her goodbye letter he goes crazy. He thinks that killing himself "will show her" and he actually pulls the trigger... but then he finds himself in the strangest situation. He seems to be alright, but also the only one that is. Everything and everyone is frozen, people are like statues. He seems to be the only one that can move about, until he meets a dog called Major and a man called Erickson.
Erickson tells him it's his fault, an experiment gone a bit wrong, sort of, so time froze and only those that were between life and death in that precise instant can now move (the dog was probably hit by a car, it seems). To put things right and get time moving again he simply needs to add power to his machine (still working) and since they can't move things that are frozen, so they can't use the wire in the room, they make one. Upon Dave suggestion, they strip each other of everything that might be used as a wire, using coins, keys, and stuff. When time moves again, he finds himself alive because the old gun had not worked properly, and Helen is in the room with him, she came back for him. He's decided to change his life for the better, now that he's had a second chance. Only six minutes have passed since he fired the gun, so he believes his adventure impossible, just a dream, but then he realizes it was not a dream when he reads of Erickson's death, with the details of the poor dog's presence and what's more, the "chain of small metal objects" they had made together.
Now, why he was frozen too since apparently he was nowhere near death at all is another matter...
