And the machine gunners had died as well, for which Rutledge, disbelieving, had been given a medal and sent back into the fighting as a bloody example. Without rest or respite: the war needed men.

As the hellish summer of 1916 dragged into agonizing stalemate for two more years, Rutledge had carried out his duties barely aware of anything except the incessant voice of Hamish in his head. He had wanted to die, had tried to die, and in spite of war and pestilence, he had lived. To come home a hero. To come home a man hardly able to speak. Bringing a dead man with him.

The doctor, Fleming, had done his work well. In June 1919, Rutledge had returned to the Yard, declared fit for duty. His secret went with him. Not even Frances knew how much it had cost Rutledge to struggle back to his former skills. A murderer standing in judgment of murderers. Nor had Hamish made it easy, standing constantly at his shoulder and condemning him. They had worked out, in time, a relationship that was more a stalemate than anything else. It was only that when he, Rutledge, was most vulnerable, Hamish was the first to sense it. As if, Rutledge sometimes thought, the dead man had taken his revenge.

Not even Fleming, with all his medical skills, could wipe out memory. Or guilt.

Cold comfort on a dark, rainy night of bad dreams and a haunting voice from the trenches.

After a time, Rutledge made himself go back to his bed, draw the sheets over his shoulders again, and close his eyes.

But when the September dawn broke grayly over London, he hadn’t slept.

IN THE LIGHT of day, Rutledge could pin down with some certainty what had precipitated the dream. It was the letter that had arrived in the previous morning’s post. He hadn’t opened it for several hours, knowing who it was from and what it demanded of him. Finally, after it had seemed to burn a hole in his coat pocket as well as his conscience, he had taken the letter out and broken the ornate seal.

His godfather, David Trevor, had written from Edinburgh, saying,

You’ve made a dozen excuses. Don’t make another one. Come to see me. I miss you, Ian, I want to see for myself that you’re alive and well. If that grim devil Bowles won’t give you leave, come anyway. My doctor will tell him you need a rest. And for that matter, so do I. Loneliness is the very devil!
