"Take care; it's like a sheet of ice."

The doctor slid and staggered round to the front of his car, the two front wheels of which were deeply sunken in the snow and slush of the ditch. He made a disconsolate examination by the light of the lamps.

"Stuck as tight as wax. Now, what the deuce are we to do?"

"Can't we move her? asked Grace.

"Not much chance of it, but we might as well try."

Grace got down, and they strained at the car, but without any success.

"No use," said the doctor briefly. "I think you two had better stay here while I get back to Questerham—we're nearer Questerham than Plessing, I fancy—and bring something out. Though, good heavens! I'd forgotten it's Christmas Eve. What on earth shall I get?"

"I can authorize you to call up one of the ambulance cars."

"That's an idea. I'm sorrier than I can say to leave you on the roadside like this," said the doctor distractedly. "Put the rug round you both, and if anything comes past, get a lift. The car will be all right. I defy the most determined thief to make her move an inch. H'm! I must take one of these lamps, and I'll make as much haste as this confounded sheet of ice will allow."

"Wait!" cried Grace. "I can hear something coming, I think."
