I glanced at the clock on the car, and saw that we had been just eighteen minutes, then up we got, and, without much preliminary, moved away again tearing at breakneck speed through Ottery St Mary and a dreary little place called Honiton Clyst, then over a bad road among small and dingy houses from Heavitree into Exeter. At the Gordon memorial-lamp we took the right-hand road, found the tram-line and passed up Paris Street into High Street, and on to the cathedral, where we pulled up before the "Clarence," hoping to obtain some news of the blue "Mercedes." It, however, had not been seen. At Pople's, at the "Globe" and the "Half Moon" we inquired, but without success. The car had not been seen in any of the main streets of the city, therefore we could only conclude that it had passed round the outskirts and taken either the Crediton or the Teignmouth road. From south of the city a dozen different ways lead off the Okehampton road, therefore it seemed certain that our unfortunate accident had negatived all our attempts to overtake Mr Murray and his party. Again we were thwarted, until Gibbs suddenly recollected that in Paris Street we had passed a cycle works where petrol was sold, and we turned the car and made eager inquiry there. Yes. A big blue car had stopped there, and refilled its tank about an hour before. The chauffeur had inquired the road to Plymouth, and the manager had advised him to take the road by Bickington, Buckfastleigh and Ivybridge. The distance to Plymouth, we were told, was forty-four miles, therefore thanking our informant we reversed the car and were soon out again on the old coach-road through Alphington and Shillingford, hoping that some similar mishap to that which had occurred to us might delay the party we were endeavouring to overtake. Again we raced along against time, up over the Great Haldon hills where we had grand views across the open country, through old-fashioned villages of the true Devon type, past a quaint old mill with high sloping roof, and narrowly escaping a collision with a farmer's cart just as we were entering Bickington. Twice we inquired of men we met on the road whether they had seen the car, and each reply was in the affirmative. Therefore we kept an eager look-out far ahead to distinguish the receding cloud of dust which would betray its presence. At full speed we tore along, the motor humming its rhythmic music and the dust rising in a dense column behind. I shrewdly suspect that before starting Gibbs had smeared a little oil across part of the number both front and rear, in order that the dust should render it puzzling to any lurking constable.
