“I snuck out to go to the concert.” Jason began. “No one was meant to know; I got the tickets and jumped out my window. I was going to take the car because the concert had already started and I didn’t want to miss more than I had.” He stopped, tears streaming down his face and Jane suddenly saw him for what he was. A kid. A kid who made a mistake. For a split second she felt badly for him until she realised that he was a kid who had run over his grandfather and left him for dead in the street.

“I didn’t notice that Gramps had cut the lawn.” Both women frowned at him. “He moves the gnomes when he does.” Jason explained. “I tripped on the gnome and it smashed, I swore and tried to get to the car but I could hear them getting up inside. So I rushed to try and get in the car but the key wouldn’t go.”

 ‘Explains the lack of damage to ignition barrel’ Jane thought. All the pieces were falling neatly into place. Except one.

“I saw Gramps coming out the door; he was trying to get the keys. I panicked and threw it into reverse. I didn’t know he’d hold on to the car.” Jason’s voice crumbled and he resigned himself to his grief. “I didn’t mean to hurt him.” He repeated.

“How’d the car get back on the drive?” Jane asked him, drawing a saddened look from Maura.

Jason wiped his nose with his sleeve again, the tissues in his lap long forgotten. “I dumped the car in a lot a few blocks away and came back to check on Gramps.” Jason’s voice trembled and shook as he spoke. “When the paramedics left, I asked my friend to move it for me. I thought if it was far away, you’d think someone had stolen it. I didn’t know he’d bring it back here. He didn’t have anything to do with it, it was all me.” Jason got to his feet.

“I killed him. I didn’t mean to do but it was my fault.” Jason held out his hands, expecting Jane to handcuff him there and then. As he finally tried to meet her gaze, his eyes were drawn to a figure behind the detective.
