Robert Confronts Dave About Allen, Explained: cancel each other out

Graysmith arrives at Toschi's house convinced Arthur Leigh Allen is the Zodiac and refuses to leave until he's heard out. Toschi, exhausted, argues the case is all circumstantial — “All the evidence said no” — and that two handwriting opinions simply cancel each other out. What looks like a fight is really obsession versus burnout.

What happens

Graysmith shows up at Toschi's house in the middle of the night, shouting through the window that he has the name: Arthur Leigh Allen. Toschi refuses to listen and reaches for the phone. Inside, Graysmith lays out a timeline of Allen's life next to the Zodiac's letters, while Toschi answers with the evidence that never added up.

Robert Confronts Dave About Allen, explained

What's really going on

The scene stages the collision of two kinds of certainty. Graysmith has pattern recognition and conviction; Toschi has the case file and the memory of every dead end. Graysmith's timeline is compelling — Allen is fired and exposed, then the letters start; Allen is watched, then the letters stop; Allen is arrested, and they stay stopped — but Toschi keeps landing the counterpunch: “All the evidence said no.” The two handwriting opinions don't settle anything, and no physical evidence was ever found in the trailer. What's really happening is that one man is refusing to accept an open case, and another is refusing to reopen one.

Theme

JusticeGraysmith tries to turn a lifetime of circumstantial evidence into a case, while Toschi explains why evidence that doesn't hold up can't convict.
PhilosophyThe argument contrasts two ways of knowing: conviction built from patterns, and proof that must survive a courtroom.

What you'll learn

  • The birthday was the one slip: he had to kill because it was his birthday.
  • Of 2,500 suspects, only Leigh Allen ever wrote Toschi a letter.
  • Forty-eight hours after the refinery interview he moved to another county.
  • Door to door from Darlene's pancake house to Allen's is less than 50 yards.

Listen for

  • made a mistake — flap
  • get that name — elision
  • each other out — liaison
  • side by side — liaison
He is silent for three years.

Part of Graysmith's timeline: the killer stops writing for years while Allen is out of reach, a gap he treats as meaningful.

We should have found one of those things in that trailer.

Toschi's admission of the case's hole: despite searching Allen's trailer, none of Stine's stolen belongings ever turned up.

Now, Vallejo is a small town, but it's not that small.

Toschi's caution: even a small town holds many people, so two shared names don't prove the Leigh in the file is Leigh Allen.

Using a typewriter is not a crime.

Toschi dismisses a supposed clue: typing an apology letter proves nothing, since anyone is free to use a typewriter.

Questions about this scene

Why does Graysmith think Allen is the Zodiac?

He lines up a timeline: Allen is fired and exposed as a pedophile, then the letters begin; once he's watched, the letters stop; once he's arrested, they stop for years; after his release, a new letter arrives.

Why does Toschi refuse to reopen the case?

Every item is circumstantial, and the physical evidence that should have been in Allen's trailer was never found. He also notes that handwriting experts contradict each other, so the case could not survive a courtroom.

Why do the two handwriting experts matter so much?

One disqualified Allen's handwriting and the other said not to exclude him on that basis. If it went to trial, the defense could put the first expert on the stand, so the two opinions cancel each other out.

What does 'on to someone' mean?

It means having noticed that someone is up to something. When one of them argues that Allen knew 'you were on to him,' he means Allen sensed he was being investigated and went quiet.
