"What harm can the letter do, you fool?" said M. Charolais. "It's Sunday. We want them knocked silly for to-morrow, to get hold of the coronet. Oh, to get hold of that coronet! It must be in Paris. I've been ransacking this chateau for hours."

Jean opened the door of the outer hall half an inch, and glued his eyes to it. Bernard had done the same with the door opening into the drawing-room. M. Charolais, Pierre, and Louis were opening drawers, ransacking them, and shutting them with infinite quickness and noiselessly.

"Bureau! Which is the bureau? The place is stuffed with bureaux!"

growled M. Charolais. "I must have those keys."

"That plain thing with the bra.s.s handles in the middle on the left--that's a bureau," said Bernard softly.

"Why didn't you say so?" growled M. Charolais.

He dashed to it, and tried it. It was locked.

"Locked, of course! Just my luck! Come and get it open, Pierre. Be smart!"

The son he had described as an engineer came quickly to the bureau, fitting together as he came the two halves of a small jemmy. He fitted it into the top of the flap. There was a crunch, and the old lock gave.

He opened the flap, and he and M. Charolais pulled open drawer after drawer.

"Quick! Here's that fat old fool!" said Jean, in a hoa.r.s.e, hissing whisper.

He moved down the hall, blowing out one of the lamps as he pa.s.sed it.

In the seventh drawer lay a bunch of keys. M. Charolais s.n.a.t.c.hed it up, glanced at it, took a bunch of keys from his own pocket, put it in the drawer, closed it, closed the flap, and rushed to the window. Jean and his sons were already out on the terrace.

M. Charolais was still a yard from the window when the door into the outer hall opened and in came M. Gournay-Martin.

He caught a glimpse of a back vanishing through the window, and bellowed: "Hi! A man! A burglar! Firmin! Firmin!"

He ran blundering down the hall, tangled his feet in the fragments of the broken chair, and came sprawling a thundering cropper, which knocked every breath of wind out of his capacious body. He lay flat on his face for a couple of minutes, his broad back wriggling convulsively--a pathetic sight!--in the painful effort to get his breath back. Then he sat up, and with perfect frankness burst into tears. He sobbed and blubbered, like a small child that has hurt itself, for three or four minutes. Then, having recovered his magnificent voice, he bellowed furiously: "Firmin! Firmin! Charmerace!

Charmerace!"

Then he rose painfully to his feet, and stood staring at the open windows.

Presently he roared again: "Firmin! Firmin! Charmerace! Charmerace!"

He kept looking at the window with terrified eyes, as though he expected somebody to step in and cut his throat from ear to ear.

"Firmin! Firmin! Charmerace! Charmerace!" he bellowed again.

The Duke came quietly into the hall, dressed in a heavy motor-coat, his motor-cap on his head, and carrying a kit-bag in his hand.

"Did I hear you call?" he said.

"Call?" said the millionaire. "I shouted. The burglars are here already. I've just seen one of them. He was bolting through the middle window."

The Duke raised his eyebrows.

"Nerves," he said gently--"nerves."

"Nerves be hanged!" said the millionaire. "I tell you I saw him as plainly as I see you."

"Well, you can't see me at all, seeing that you're lighting an acre and a half of hall with a single lamp," said the Duke, still in a tone of utter incredulity.

"It's that fool Firmin! He ought to have lighted six. Firmin! Firmin!"

bellowed the millionaire.

They listened for the sonorous clumping of the promoted gamekeeper's boots, but they did not hear it. Evidently Firmin was still giving his master's instructions about the cars to Jean.

"Well, we may as well shut the windows, anyhow," said the Duke, proceeding to do so. "If you think Firmin would be any good, you might post him in this hall with a gun to-night. There could be no harm in putting a charge of small shot into the legs of these ruffians. He has only to get one of them, and the others will go for their lives. Yet I don't like leaving you and Germaine in this big house with only Firmin to look after you."

"I shouldn't like it myself, and I'm not going to chance it," growled the millionaire. "We're going to motor to Paris along with you, and leave Jean to help Firmin fight these burglars. Firmin's all right--he's an old soldier. He fought in '70. Not that I've much belief in soldiers against this cursed Lupin, after the way he dealt with that corporal and his men three years ago."

"I'm glad you're coming to Paris," said the Duke. "It'll be a weight off my mind. I'd better drive the limousine, and you take the landaulet."

"That won't do," said the millionaire. "Germaine won't go in the limousine. You know she has taken a dislike to it."

"Nevertheless, I'd better bucket on to Paris, and let you follow slowly with Germaine. The sooner I get to Paris the better for your collection. I'll take Mademoiselle Kritchnoff with me, and, if you like, Irma, though the lighter I travel the sooner I shall get there."

"No, I'll take Irma and Germaine," said the millionaire. "Germaine would prefer to have Irma with her, in case you had an accident. She wouldn't like to get to Paris and have to find a fresh maid."

The drawing-room door opened, and in came Germaine, followed by Sonia and Irma. They wore motor-cloaks and hoods and veils. Sonia and Irma were carrying hand-bags.

"I think it's extremely tiresome your dragging us off to Paris like this in the middle of the night," said Germaine pettishly.

"Do you?" said the millionaire. "Well, then, you'll be interested to hear that I've just seen a burglar here in this very room. I frightened him, and he bolted through the window on to the terrace."

"He was greenish-pink, slightly tinged with yellow," said the Duke softly.

"Greenish-pink? Oh, do stop your jesting, Jacques! Is this a time for idiocy?" cried Germaine, in a tone of acute exasperation.

"It was the dim light which made your father see him in those colours.

In a bright light, I think he would have been an Alsatian blue," said the Duke suavely.

"You'll have to break yourself of this silly habit of trifling, my dear Duke, if ever you expect to be a member of the Academie Francaise,"

said the millionaire with some acrimony. "I tell you I did see a burglar."

"Yes, yes. I admitted it frankly. It was his colour I was talking about," said the Duke, with an ironical smile.

"Oh, stop your idiotic jokes! We're all sick to death of them!" said Germaine, with something of the fine fury which so often distinguished her father.

"There are times for all things," said the millionaire solemnly. "And I must say that, with the fate of my collection and of the coronet trembling in the balance, this does not seem to me a season for idle jests."

"I stand reproved," said the Duke; and he smiled at Sonia.

"My keys, Sonia--the keys of the Paris house," said the millionaire.

Sonia took her own keys from her pocket and went to the bureau. She slipped a key into the lock and tried to turn it. It would not turn; and she bent down to look at it.

"Why--why, some one's been tampering with the lock! It's broken!" she cried.
