Marino and Detective Sil Machado live on the same block in their West Cambridge neighborhood and ride motorcycles together. They’re both into boxing and go to the same gym. It seems they’ve become close friends.

“What Toby told me last night was pretty skimpy, not much known at the time,” Marino adds. “Victim’s a chronic alcoholic. Appears he opened the wrong door on his way to the bathroom and fell down the basement stairs.”

“Hopefully Luke got a STAT alcohol. Have you talked to Bryce or heard from him?” I cover my hair with a surgical cap.

“He left around eleven.” Marino is looking me up and down. “You should suit up before walking in here,” he says, as if I need him to remind me of protocols.

“What do you mean left? Left where? Here?”

“Apparently had to take his cat to the vet for what he claims is an emergency. He said he’d already let Steward know we’re just getting back from a scene. Apparently he’s cross-examining the witness who’s right before you and it’s going slow, and after that he’s going to ask for a break.” Marino picks up a six-inch plastic ruler and sticks a blank label on it. “But it’s not smart to assume you’ll be cut any slack for being late, not with that asshole’s dream team.”

He means Channing Lott’s defense attorneys.

“There’s no way around my being late,” I reply. “Dan needs to let the judge know that matters are slightly out of my control at the moment.”

“If we drove there right now you’d make it.”

I imagine myself walking into the courtroom wearing wet boots and a drysuit liner so Channing Lott’s attorneys can have fun with me.

“We got a case number?” Marino opens a drawer and finds several permanent markers.

I tell him what it is, and he writes it and the date on the ruler’s label as I unfold a disposable lab coat. It rustles as I put it on over my gray liner, which I wish I didn’t have to take off anytime soon. I’m still chilled, as if my blood is several degrees cooler than it should be.

“What’s wrong with Bryce’s cat?” I ask. “Nothing serious, I hope.”

“Onions from chili they had last night; that’s my story and I’m sticking to it, even though Bryce says they’re really careful when they cook with onions. Never drops nothing on the floor or leaves a dirty bowl the cat might get into, right? Ethan and him. Mr. Slob and Mr. Clean.”

“I’m curious how you know what they had for dinner last night.” I pull examination gloves out of a box.
