Ian Peterson Timeline and Summary

Ian Peterson visits John Renfrew at Cambridge.
After hearing Renfrew and Markham's plans to send messages back in time with tachyons, he secures funding for their experiment.
Later, he flies to California where he receives a message left for him in a safety deposit box. The message is from someone at the University of California at La Jolla who received the message in the past.
Peterson tries to convince Renfrew not to send the message requesting the safety deposit message since he's curious as to what would happen if they create a paradox. Renfrew convinces him otherwise.
During a dinner at Renfrew's house, Peterson flits with Marjorie.
Later, Peterson meets a girl named Laura at a restaurant in London. The food is poisoned, though, and Peterson ends up in the hospital.
Knowing the world's about to go kaput, a still sick Peterson leaves the hospital to grab his bug out bag. He finds his wife, Sarah, having a party, but he doesn't tell her his plans and sneaks away.
He briefly stops by Renfrew's house to talk with him, but finds Marjorie alone in the dark instead; the two have a one-night stand.
Peterson travels to his country home, a place he's been fortifying with stored up food and impenetrable walls.
There, Peterson decides to wait out the end of the world as he knows it.
