Page "Secret Window" Paragraph 2

During his walk the following day, Mort is accosted by Shooter when he explains his story was published years before Shooter's existed.

He is given a three-day ultimatum by Shooter to provide the proof.

That night, Mort finds Chico, his Australian Cattle Dog, stabbed to death with a screwdriver in his neck.

Mort immediately suspects Shooter and reports the incident to Sheriff Dave Newsome ( Len Cariou ), who reacts with little enthusiasm.

Mort then drives to his house where his estranged wife Amy is living to obtain a copy of the book and stews outside as he watches her leave with her new lover Ted Milner ( Timothy Hutton ).

In New York City, Mort contacts Ken Karsch ( Charles S. Dutton ), a private investigator he used before.

Ken travels to Tashmore Lake to watch over the cabin and to interview Tom Greenleaf ( John Dunn Hill ), the only witness to Mort and Shooter's conversation.

Amy later calls saying their house was burned down, consequently destroying the copy of the book to prove his case against Shooter.

He begins to suspect Ted of hiring Shooter to harass him because of their shared animosity towards one another.
