“That’s one of the reasons I’m talking to you, Simon. I was hoping you might have an idea. I’m investigating alleged child abuse at the City Road orphanage as part of a multiple murder enquiry. I have statements from Margo McDonald, Craig Derbyshire, George Winter and William Booth, who have all stated that abuse happened at the orphanage, that you were also a victim – and that Oscar Anderson set you up for the GBH charge you’re in for. I can understand you have little to trust the police for, Simon, but I’m determined to get to the truth and won’t stand by whilst an innocent man rots in jail.”

The line fell silent again. Corstorphine could picture Simon processing the news, working the angles, trying to trust the enemy.

“Who else has gone? You said multiple murders.”

It was Corstorphine’s turn to be silent. No point in holding back, though. The press would have the names soon enough. “Oscar Anderson was killed sometime Friday, the minister Reverend Simon McLean on Sunday and the sheriff yesterday. I think it’s one of the orphans taking revenge. Do you have any idea who may be responsible, Simon? Before anyone else dies.”

“Those bastards all deserved it, and there are others out there who should be worried. I’m glad they’re all dead.”

“Who else should be worried, Simon? Give me some names.”

“You said you knew I was innocent.”

“That’s what the four statements I have say, yes.”

“And you’re going to get me out of here?” His voice held the first sign of hope, a drowning man clutching a straw right enough, but still having something to hold on to.

“I’m putting the wheels in motion, Simon. I can’t promise it will happen any time soon but with this new information I’m confident we can get you released, yes.’ Corstorphine held back, feeling the fish nibbling on the line. Strike too soon and he’d lose the catch.

“I don’t know who’s taking them out, but I’m fucking glad he’s out there. You’d better tell that old detective to watch out – he knew fine well what was going on here and did nothing. There’s only one other bastard who needs killing. Lord fucking Lagan! Hope he gets to him before you do.”

“There’s nothing else you can give me? No idea who we should be looking for?”

Simon’s laugh echoed down the line. “Man. I’ve been in here for years – how the fuck am I meant to know who it is?”

Corstorphine let him know they’d be making a return trip to take a written statement and put the phone down.
