“What do you want?” Maddox snapped, “get out, I’m busy.”

“I’m sorry, Mr. Maddox, sir,” Murphy said in a low voice, “but, I’m leaving. I’ve just come to say good-bye.”

“What do you mean… you’re leaving? You’ve been with me twenty years,” Maddox said, startled.

“I know that, sir,” Murphy replied, shaking his bead sadly, “it’ll be a blow to the wife when she hears about it, but I’ve got to go. I’m conscientious, sir, and I don’t think I’m fit any more for the job.”

Maddox got to his feet. “What are you drivelling about?” he roared. “What is this? I warn you, Murphy, if this is a gag, I’ll make you sorry. I won’t have people wasting my time. Now, go downstairs and look after the doors. If you’ve been drinking, sleep it off. You’re an old trusted servant and I’ll overlook this, if you’ll get out.”

Murphy approached him. “It’s not that, sir,” he said mournfully, “my brain’s given way.” Maddox took a hasty step back, “Your brain?” he repeated uneasily.

Murphy nodded. “Yes, sir,” he said, “it was all right this morning, but it’s gone now. I’ve got to go. I might do something I’d be sorry for.”

“How do you know your brain’s given way?” Maddox asked, behind his desk by now.

“I’m hearing things, sir,” Murphy said. “Voices in my head.”

Maddox appealed to Harriet. “Do people hear voices in their heads when their brains give way?”
