"Only by air," said my cousin. "Outside a track, thirteen miles in fourteen minutes is just a shade too thick; Still, there's nothing the matter with the road after Irun, and Evelyn may be delayed getting through." He swung himself into Ping and started her up. My sister and Jill scrambled aboard while he was turning her round. As he headed for the Calle Mayor-- "Stop!" shrieked his sister. "The scent, Jonah, the scent. We've got to go back." Jonah threw out the clutch. "We'll get that!" cried Adèle. "You go on, and we'll follow." "Right." The next moment Ping had dropped out of sight. It was perhaps five minutes later that, after conjuring Berry to stay where he was and move the car for nobody, I assisted my wife on to the pavement. When Fuenterrabia was planned, an eleven-feet-six wheel-base was not considered. To wheedle Pong to the mouth of the Calle del Puerto had been a ticklish business, and I had berthed her deliberately with an eye to our departure for the city gate, rather than to the convenience of such other vehicles as might appear. Besides, for my brother-in-law to have essayed manoeuvres in such surroundings would have been asking for trouble. As Adèle and I hastened along the street-- "We must look sharp," I insisted.

That she was most apprehensive was perfectly plain.... Half-way between curtain and table she stopped. Then she put a hand to her throat. "_Madame_ desires something?" "Some scent, please," said Adèle reassuringly. Her cheerful tone appeared to encourage the girl. And when my wife pointed to the green phial and asked to be sprayed with its contents, I could have sworn her attitude was that of relief. In a flash she had produced a small square of linen. This she handed to Adèle. "Smell, _Madame_. See, it is scentless. _Pardon_." She sprayed it with scent. "_Voilà_. That is the 'Black Lily.'" Adèle passed it to me. The scent was exquisite. "It's delicious," said Adèle. "Yes, _Madame_, it is good. Will _Madame_ sample the others?" "If you please." Fresh squares of linen were produced, offered for inspection, and sprayed....
