Nella jumped into the next carriage--an open one--that came up.
'Follow that carriage,' she said succinctly to the driver in French.
'Bien, madame!' The driver whipped up his horse, and the animal shot forward with a terrific clatter over the cobbles.

It appeared that this driver was quite accustomed to following other carriages.
'Now I am fairly in for it!' said Nella to herself.

She laughed unsteadily, but her heart was beating with an extraordinary thump.
For some time the pursued vehicle kept well in front.

It crossed the town nearly from end to end, and plunged into a maze of small streets far on the south side of the Kursaal.
