it. If it has gone, go to Jason's and get one directly, Oakshott."

In five minutes the baronet returned.

"I can't get a trap anywhere," said he dismally, "but I've got Jason to
send a horse."

"That will do," said Railsford, hurrying down.

"Will it do?" groaned Dig. "_I_ can't go too! Oh, Mr Railsford,"
shouted he, as the master was jumping into the saddle, "what road shall
you come back by?"

"Maiden Hill," said the master, digging his heels into the horse's side.

With a heavy heart Digby watched him start, and then putting on his cap
determinedly, followed him on foot into the night and rain.

"I shall do it in two hours and a half," said he to himself, "if I trot
part of the way. What a cad I was to leave him up there!"

It was not till bed-time at Railsford's that fellows generally became
aware that the master and two of the boys were missing. Railsford and
Oakshott had both been seen in the school after their return from the
picnic. Railsford had, of course, depended on the boy to explain his
sudden absence, and Dig had been too miserable and excited to think of
telling anybody as he started on his weary tramp.

The first inquiry for the missing ones came from the doctor, who, after
his interview with Felgate, sent a messenger over to the Master of the
Shell to request his presence in the head-master's study at once. The
messenger returned to report that Mr Railsford was not in, and no one
knew where he was gone. Then, the hue and cry being once raised, it
appeared that Arthur and Dig's study was also empty and that its owners
were nowhere to be found.

Presently the school gatekeeper reported that on coming up from the town
just now he had seen Mr Railsford galloping on one of Jason's horses in
the direction of the London road! And Munger, who had been out of
bounds, reported in private (because the disclosure might get him into
trouble if it came to the ears of the authorities) that just as he was
sneaking in at the gate he met Sir Digby Oakshott, Baronet, sneaking
out.

The doctor, who might never have heard of the affair, had he not chanced
to want to see Railsford particularly that evening, walked over to the
house about bed-time and interviewed Ainger.

"Have you the slightest idea what it all means?" asked the head-master.

"Not the slightest, sir," said Ainger shortly. If he had had, he would
have spoken long ago, as the doctor knew--or should have known.

"No one is to stay
