“Oh, it will do very well.  Thanks.  By the way, you’ve not had a young lady here asking for this key to-day?”

The woman shook her head.

“No one’s been over the place for a long time.”

“Thanks very much.”

They retraced their steps to the Moat House.  As the front door swung back on its hinges, protesting loudly, Julius struck a match and examined the floor carefully.  Then he shook his head.

“I’d swear no one’s passed this way.  Look at the dust.  Thick.  Not a sign of a footmark.”

They wandered round the deserted house.  Everywhere the same tale.  Thick layers of dust apparently undisturbed.

“This gets me,” said Julius.  “I don’t believe Tuppence was ever in this house.”

“She must have been.”

Julius shook his head without replying.

“We’ll go over it again to-morrow,” said Tommy.  “Perhaps we’ll see more in the daylight.”

On the morrow they took up the search once more, and were reluctantly forced to the conclusion that the house had not been invaded for some considerable time.  They might have left the village altogether but for a fortunate discovery of Tommy’s.  As they were retracing their steps to the gate, he gave a sudden cry, and stooping, picked something up from among the leaves, and held it out to Julius.  It was a small gold brooch.

“That’s Tuppence’s!”

“Are you sure?”

“Absolutely.  I’ve often seen her wear it.”

Julius drew a deep breath.

“I guess that settles it.  She came as far as here, anyway.  We’ll make that pub our head-quarters, and raise hell round here until we find her.  Somebody must have seen her.”

Forthwith the campaign began.  Tommy and Julius worked separately and together, but the result was the same.  Nobody answering to Tuppence’s description had been seen in the vicinity.  They were baffled—­but not discouraged.  Finally they altered their tactics.  Tuppence had certainly not remained long in the neighbourhood of the Moat House.  That pointed to her having been overcome and carried away in a car.  They renewed inquiries.  Had anyone seen a car standing somewhere near the Moat House that day?  Again they met with no success.

Julius wired to town for his own car, and they scoured the neighbourhood daily with unflagging zeal.  A grey limousine on which they had set high hopes was traced to Harrogate, and turned out to be the property of a highly respectable maiden lady!

Each day saw them set out on a new quest.  Julius was like a hound on the leash.  He followed up the slenderest clue.  Every car that had passed through the village on the fateful day was tracked down.  He forced his way into country properties and submitted the owners of the motors to a searching cross-examination.  His apologies were as thorough as his methods, and seldom failed in disarming the indignation of his victims; but, as day succeeded day, they were no nearer to discovering Tuppence’s whereabouts.  So well had the abduction been planned that the girl seemed literally to have vanished into thin air.
