At that moment Simon Templar was not thinking about the possible consequences of being followed night and day by the heavy-footed minions of the C.I.D. His mind was entirely occupied with other consequences which struck him as being far less commonplace.

He had hailed a taxi outside the house, and as he was climbing in he heard a curious sharp crack of sound in front of him. He felt a quick stinging pain like the jab of a needle in his chin, and something like an angry wasp zoomed past his ear. As his head jerked up he saw a new spidery pattern of cracks in the window a couple of feet from his eyes — an irregular star-shaped spangle of lines radiating from a neat hole perforated in the glass, about the size of a 38-calibre bullet.

A split second later the Saint's glinting gaze was raking the street and surrounding pavements instinctively, before he realized the futility of the effort. He realized a moment afterwards that the shot could only have come from another car, which had crept up alongside the taxi so that some philanthropist could fire at him through the offside window as he boarded the cab from the pavement. As he started to search the scenery for the offending vehicle a bus crashed past, shutting off his field of vision like a moving curtain; and as it went on its bulk effectively obliterated any glimpse he might have had of a car making off in the same direction.

Fortunately the gun must have been silenced; and the taxi driver must have taken the accompanying sound effects for a combination of the cough of a passing exhaust and the clumsiness of his passenger, for he had not even looked round. As the Saint settled onto the seat and closed the door through which he had entered he grated the gears together and chugged away without any apparent awareness of the sensational episode that had taken place a few inches behind his unromantic back.

Simon took out a handkerchief and dabbed his chin where it had been nicked by a flying splinter of glass. Then he reached forward, unlatched the damaged door and slammed it again with all his strength. The glass with the bullet hole in it shattered with the impact and tinkled down Into the road.

This time the driver did look round, jamming on his brakes at the same time.

" 'Ere," he protested plaintively, "wot's all this?"

"I'm sorry," said the Saint in distress. "The door wasn't fastened properly, and I must have banged it a bit too hard. I'll have to pay you for it."

"That you will," said the driver. "Free pounds each, them winders cost."
