The chauffeur, who saw him coming, started up and climbed to his seat.

Quest took his place.
"Drive to the office," he ordered.
The man slipped in his clutch.

They were in the act of gliding off when there was a tremendous report.

They stopped short.

The man jumped down and looked at the back tire.
"Blow-out," he remarked laconically.
Quest frowned.
"How long will it take ?" "Four minutes," the man replied.
