“Yes, yes. Won’t you lie down for a little?” suggested the Prime Minister.

“Thank you so much, P.M.—no. I’ll go home, I think. If someone could tell my chauffeur—” A secretary was summoned. O’Callaghan turned to the door. The Postmaster-General made as if to take his arm. Sir Derek nodded his thanks, but walked out independently. In the hall the secretary took his coat from the butler and helped him into it.

“Shall I come out to the car, Sir Derek?”

“No, thank you, my boy. I’m my own man again.” With a word of farewell to the Prime Minister he went out alone.

“He looks devilish ill,” said the Prime Minister irritably. “I hope to heaven it’s not serious.”

“It’ll be damned awkward if it is,” said the Postmaster-General. “Poor old O’Callaghan,” he added hurriedly.

In his car the Home Secretary looked out of the window drearily. They turned out of Downing Street into Whitehall. It was a cold, gusty evening. The faces of the people in the streets looked pinched and their clothes drab and uneventful. Their heads were bent to the wind. A thin rain was driving fitfully across the window-pane. He wondered if he was going to be very ill. He was overwhelmed with melancholy. Perhaps he would die of this thing that seized him with such devastating agony. That would save the anarchists and the C.I.D. a lot of trouble. It would also save him a lot of trouble. Did he really care tuppence about his Bill or about the machinations of people who wanted to revolutionise the system of British government? Did he care about anything or anybody? He was conscious only of a pallid indifference and an overwhelming inertia. He was going to be ill.

At the top of Constitution Hill his car was held up by a traffic jam. A taxi drew up close beside it. He could see that there was a fare inside, but no more than that. The driver looked several times at O’Callaghan’s chauffeur and called out something which his man answered gruffly. O’Callaghan had the feeling that the person inside the taxi stared in at his window. He was being watched. He had experienced this sensation many times lately. He thought, with a sort of amusement, of the Prime Minister’s anxiety. He pulled a cord and the inside of the car was flooded with light.

“Give them a good view while I’m about it,” he thought grimly.
