But Prince was now beyond the reasoning power of any human voice.  The thunder rumbled and crashed overhead.  Grace, above it, could hear the whining decrease of the exhaust of the big car that had caused her steed to run away.

“Prince!  Prince!” she pleaded.

He did not heed.  Farther and farther she slipped from the saddle as his wild plunges threw her out of it.  Then there came a crash that seemed to mark the height of the storm.  A great light shone in front of Grace.  Myriads of stars danced before her eyes.

She flashed towards a house.  From it ran two little tots, and, even in that terror she recognized them as Dodo and Paul, the two Billette twins.  They were visiting a relative who lived on this road, she dimly recalled hearing Mollie say.  Evidently the children had run out in the storm.  A nursemaid caught Paul, but Dodo eluded the girl, and ran straight for the road along which Grace was plunging.

“Go back!  Go back!” screamed Grace.  “Go back, Dodo!”

But Dodo came on.  The next moment the child seemed to be beneath the feet of the maddened horse, which, a second later, slipped and fell, throwing Grace heavily.  Her senses left her.  All was black, and the rain pelted down while the lightning flashed and the thunder rumbled and roared.

CHAPTER IV

 The missing documents

“How do you feel now?  Do you think you can drink a little of this?”

Faintly Grace heard these words, as though some one, miles away, was repeating them through a heavy fog.  Myriads of bells seemed ringing in her ears, and her whole body felt as though made of lead.  Then she became conscious of shooting pains.  Her head ached, there was a roaring in it.  This was followed by a delicious drowsiness.

“Try and take a little of this.  The doctor does not think you are badly hurt.  Fortunately the horse did not fall on you.”

Again it seemed as though the voice came from the distant clouds.

Grace tried to think—­ to reason out where she was, and discover what had happened; but when she did, that same ringing of bells sounded in her ears, her head ached and she felt she was losing that much-to-be desired drowsiness.

“Try and take it.”

She felt some one raise her head, supporting her shoulders.  She struggled with herself, resolving not to give way to that lethargy.  She opened her eyes with an effort, and looked about her in wonder.  She was in a strange room, and a strange woman was bending over her, holding a glass of some pleasant-scented liquid.

“There, you have roused up, my dear, try to take this,” said the woman, with a smile.  “The doctor will be back to see you in a little while.”

“The doctor,” stammered Grace.  “Am I hurt?  What happened?  Oh, I remember, Prince was frightened by the auto, and ran away.  Where is he?” she asked in sudden terror, as a thought came to her.
