An Alsatian. Black and a dirty yellow. Very mean. It was chained up near the gate to the lot so that it couldn’t quite get out to the pavement. It looked as if it wanted to more than it wanted its next meal and the ribs showing through its scruffy hide suggested meals weren’t all that frequent. As cars drove past it strained at the chain. A man walked by on the other side of the street and the dog stretched the chain to its last link as it watched him out of sight.

I parked opposite the gate about thirty metres from the dog. It watched me and I watched it. I also looked into the yard for signs of human life. A big man wearing overalls wandered into view carrying what looked like a gearbox. He answered the description Cy had given me-190 centimetres, one hundred kilos, fortyish, ginger hair. I got out of the car and crossed the road. The dog started to bark when I was still twenty metres away and it kept on barking until I stood just outside the length of the chain. The man in the overalls looked towards the gate. He put the piece of machinery down and wiped his hands on a rag.

I took out Cy’s letter in its pure white envelope and waved it like a flag of truce. ‘Mr Peckham,’ I yelled. ‘Good news.’

The dog barked louder.

‘Call him off. I want to talk to you.’

He shook his head. I wondered whether I could hurdle the dog and get beyond the reach of the chain before it recovered. Glen might have made it; I knew I had no chance. I went back to the car and took my. 38 Smith amp; Wesson from the glove box. Back across the street I held the pistol at arm’s length. The dog was rearing up, pressing forward. If a link in the chain or the fastening to its collar gave, blood would have to flow. I lifted the gun, then brought it down slowly and pointed it at the dog’s head.

‘Don’t!’

He hurried forward, making soothing noises to the dog which responded immediately, dropping to its haunches and assuming a sort of His-Master’s-Voice position. It stayed there, growling quietly, as he stroked its ears and rubbed the thick fur around its collar. I put the gun in the pocket of my jacket.
