At that moment a bell rang in the distance. "Excuse me, sir," said Caw and went out.

"What's the man driving at?" said Alan with natural enough impatience.

"Well," his friend replied slowly, "doesn't it seem queer that the clock should have been put there simply to proclaim when the year was up? A grocer's calendar could have done that much--"

"By Jove!" Christopher's nephew strode across the room and stood staring at the timepiece. "Teddy," he said at last, "if it weren't for that blighted Green Box, I'd be imagining all sorts of--"

Caw entered with a telegram on a tray. "For you, Mr. France," he said, presenting it. "The messenger waits."

Teddy read and went rather pale.

"Not bad news, old man?" Alan asked, coming over.

"Yes, it's bad--and yet it might have been worse. Read it. Don't go, Caw--or rather, ask the messenger to wait--"

"We'll ring for you, Caw," said Alan.

The message in his hand ran on to a second sheet, and was as follows:

"Father has heard of Alan's return from B. The shock was too much, but though weak he is very glad. But I fear for him. Tell Alan whatever you think desirable. This is a last resort. Reply Queen's Road P.O.

"DORIS."

In Alan's heart an angry question flared up and went out. Why this appeal to Teddy? Nay, enough that she needed help. Besides, she might not have felt at liberty to address him direct. He looked up with a tender expression and met his friend's eye--good honest eyes that were bound to betray a secret such as Teddy's.... It struck Alan then that his return to home life might have consequences more momentous than he had dreamed of. With a slight flush on his tanned skin he went back to his chair by the fire, and, motioning Teddy to one opposite, said:--

"Just do what Doris says, old man. Tell me whatever you think desirable, and no more. And before you begin, I'll remind you that in all our talk to-day I have never once uttered a word against Lancaster. The man has been simply the victim, the tool, of Bullard. Caw thinks the same, and my uncle said as much just before he died. You and I know that he is no villain. And why delay sending an answer to this wire? There can be only one answer. You'll find forms on the table."

"Won't you send it, Alan?"

"I'll send one to Lancaster himself."

"Better not."

"Why?"

"Mrs. Lancaster is on Bullard's side."

"Ah!"

"Besides," Teddy continued, rather awkwardly, "I feel that you ought to hear what I have to say before you promise Lancaster--"

"I was merely going to ask him not to worry about anything."

"Exactly! But I had better tell you at once that in order to follow your advice Lancaster would require to have twenty-five thousand pounds."

Alan gave a soft whistle. Then he laughed pleasantly. "You may tell Doris to tell him not to worry about anything. I'm owing him fifteen hundred and interest as it is."

"Alan!" cried Teddy, incredulous; "you don't really--"

"Oh, shut up! Put it any way you like, but don't keep Doris waiting.

Listen! How will this do? 'Tell father with Alan's regards, no cause for anxiety in any direction, and he hopes to see you both almost immediately. Guard this from B.' ... Anything else?"

"I--I'd like to mention that the box is here."

"The box! But what in creation does Doris know--"

"I'll be telling you in a minute," Teddy interrupted, looking hot and miserable.

"All right. Go ahead."

Teddy added to the message: "Surprised to find box safe here." Then, with his pencil dabbing the blotting-paper, he said: "Alan, if you don't mind my suggesting it, I think she'd like a word from you--for herself." He had evidently forgotten that he had brought no "word" for Alan.

The latter did not reply at once. "You might put," he said slowly, his gaze on the fire, "'Trust Alan,' or words to that effect--No, don't say anything."

Teddy gave him a puzzled glance, sighed, and completed the message.

Alan rang the bell, remarking: "Caw will be interested to know that it was Bullard who was here last night with his petards. Pretty clever chap, Bullard. But what on earth made him return the box?"

"I can tell you that also," said Teddy, as Caw came in for the telegram.

"Quick as you can, Caw," Alan said. "Mr. France has more to tell us."

The friends smoked in silence till the servant came back.

This time Teddy reserved nothing save Doris's promise to marry Bullard at the end of a year. That, he felt, was for Doris herself to tell. Beyond an occasional exclamation his recital met with no interruption. When he had made an end there was a long pause while Alan and Caw filled up mentally a few more of the gaps in their knowledge. The latter was sadly upset by the revelation of the stones being paste.

"I wonder," said the former, "who the man was who opened the box for Bullard?"

"Lancaster, I fancy, will be able to tell you. Bullard seems to have rather a choice set of a.s.sistants. Doris described him as a dreadful-looking man!"

"May I ask you a question, Mr. Alan?"

"Certainly--as many as you like."

The servant was gazing at the carpet. "When Mr. France informed us that the diamonds in the Green Box were false, why, sir, did your eyes jump to the clock?" He rose without waiting for the answer. "And may I remind you, gentlemen, that you are dining at Dr. Handyside's in twenty minutes from now?" He was going out when Alan recalled him.

"Have you the address of the chap who made the clock, Caw?"

"I have, sir."

"Then wire him now asking him to come here in the morning. And, by the way, Caw--" Alan hesitated.

"Sir?"

"You don't mind being left alone this evening?"

"No, sir. I hardly expect that anything will happen _this_ evening.

Besides, it is evidently known now that you are at home. Also, which I omitted to mention before, there is the bell wire to Dr.

Handyside's study."
