Cassie and I didn't look at each other, didn't move a muscle, but the realization shot between us like a jolt from an electric fence. One reason we had taken Jessica's Tracksuit Shadow story quite so seriously was that Damien had put the very same guy practically at the scene of the crime.
"When we talked to you," I said, after only a fractional pause, "you invented a big guy in a tracksuit, to throw us off."
"Yeah." Damien looked anxiously from one of us to the other. "Sorry about that. I just thought…"
"Interview suspended," Cassie said, and left. I followed her, with a sinking sensation in my stomach and Damien's faint apprehensive "Wait-what…?" drifting after us.
By some shared instinct, we didn't stay in the corridor or go back to the incident room. We went next door, into the interview room where Sam had been questioning Mark. There was still debris strewn on the table: crumpled napkins, Styrofoam cups, a splatter of dark liquid where someone had banged down a fist or shoved back a chair.
"All
"Apparently, yeah," I said.
"When he finally said it…God, I think my jaw practically hit the floor. Champagne tonight, whenever we're finished, and lots of it." She let out a deep breath, leaned back against the table and ran her hands through her hair. "You should probably go get Rosalind."
I felt my shoulders tighten. "Why?" I asked coolly.
"She doesn't like me."
"Yes, I'm aware of that. Why should anyone go get her?"
Cassie stopped in midstretch and stared at me. "Rob, she and Damien gave us the same exact fake lead. There has to be some connection there."
"Actually," I said, "Jessica and Damien gave us the same fake lead."
"You think Damien and
"I don't think anyone's in on anything. What I do think is that Rosalind has been through just about enough for one lifetime, and that there's not a chance in hell that she was an accomplice to her sister's murder, so I don't see the point of dragging her in here and putting her through even more trauma."
Cassie sat back on the table and looked at me. There was an expression in her eyes that I couldn't fathom. "Do you think," she inquired eventually, "that that little sap came up with this all by himself?"
"I don't know and I don't care," I said, hearing echoes of O'Kelly in my voice but unable to stop myself. "Maybe Andrews or one of his buddies hired him. That would explain why he's dodging the whole motive thing: he's scared they'll go after him if he rats them out."
"Yeah, except we don't have one single connection between him and Andrews-"
"Yet."
"-and we do have one between him and Rosalind."
"Did you hear me? I said,
"By the time the records come back, Damien'll have calmed down and got himself a lawyer, and Rosalind will have seen the arrest on the news and she'll be on her guard. We pull her in right now and we play them off each other till we find out what's going on."
I thought of Kiernan's voice, or McCabe's; of the vertiginous sensation as the ligaments of my mind gave way and I floated off into that soft, infinitely welcoming blue sky. "No," I said, "we don't. That girl is
"No we don't, Rob," Cassie said sharply. "No we don't. That's Victim Support's job. We have a responsibility to Katy, and a responsibility to try and find out the truth about what the hell happened here, and that's
"And if Rosalind goes into a depression or has a nervous breakdown because we've been harassing her? Are you going to claim that's Victim Support's problem, too? We could damage her for life here, do you understand that? Until we have something a whole lot better than a minor coincidence, we leave that girl the hell alone."
"Minor
