Sheldon Hawkes looks at the plasma screen at the lab, analyzing the threatening note. "A Presto" it had read.

Mac walks in. "You got anything off the note?" Mac asks.

"Swabbed for epithelials. Sent it to DNA" Hawkes replies. He turns to Mac. "Is Danny alright?"

"Lindsay's with him" Mac answers. "Still unconscious."

Hawkes heaves a deep sigh. "I looked at Danny's injuries, Mac. If Lindsay had been late by a minute, Danny would've…"

"But she wasn't" Mac replies. "How about the handwriting, any hits on the database?"

"None so far" Hawkes replies. "But take a look at how the handwriting is slightly slanted to the right. And the marks are heavier on the left, not heavy althroughout"

"Writer was left-handed" Mac concludes. "Can you put up somebody's case file on the screen?"

"Who's?" Hawkes asks.

"Sonny Sassone's. I want to see his signature" Mac answers.

Hawkes punches a few commands on the computer and in a matter of seconds, Sonny Sassone's file is on the screen.

"Look at the "s" on Presto" Mac observes.

"Consistent with the "s" on Sassone" Hawkes answers.

"Get the epithelial DNA results as soon as possible and match it to the blood on the carpet." Mac says as he leaves the room. "It's the only way we can prove that Sonny Sassone wrote that note and tried to kill Danny."
