"Then it will be too late. I ask you to put them away every night in the strong-room. Bertha can take the case there, when she has dressed you for dinner."

"Very well," said Lady Charvington, who was impatient to return to a very interesting book she was reading. "I'll tell Bertha, though I'm sure if the case is in my bedroom she can look after it well enough."

"Pooh. She's half blind. Why don't you get a better maid?"

"Bertha's been with me all my life, and I shall keep her until she is past work. You have no heart, Charvington," she ended virtuously.

"She's past work now," said her husband, as he stalked from the boudoir.

Nothing more was said, but had Charvington been in the house on that Wednesday evening he would either have asked his wife if the jewels had been put away, or have attended to the matter himself. But during the day he suddenly decided to go up to London in order to see a private detective whom he had employed before on various delicate matters. It would be just as well, thought Charvington, to have this man in the house on Thursday evening. Then, if the two thieves alluded to by Canning did arrive, the man could lay hands on them. Not that Charvington wished to make a public case of the matter, since, as he had hinted to Lesbia, he was anxious to avoid scandal in connection with Tait, whom he shrewdly suspected of having a hand in this new piece of rascality. For this reason he went up to London to engage the private detective, and remained in town for the night. Next day he purposed coming back with his assistant and then the matter could be settled quietly. Lady Charvington would not lose her jewels, and there would be no trouble--publicly at all events--in connection with Mr. Michael Tait.

All that Wednesday Lesbia enjoyed herself on the river with her host's daughters, in spite of the launch's breaking down temporarily on the way back, in consequence of some accident to the engines. Consequently it was not until seven o'clock at night that the three girls arrived in Maidenhead, and it was thirty minutes past when they came to The Court. Lady Charvington, who had been anxious about their non-arrival, expressed herself as annoyed at their failure to be in to dinner, which was at seven o'clock. She sent a message saying that Agatha and Lena were to dine in their school-room with the governess. Lesbia feeling herself a culprit--although on the face of it not one of the three was to blame--decided to dine with the girls and to make her apologies afterwards to Lady Charvington. And a very merry dinner they had, for the governess was a charming, middle-aged lady, who made everything very pleasant. And then the love of Agatha and Lena for their newly-found cousin grew with every hour. On the whole, Lesbia enjoyed that school-room meal more than the splendid dinner of the previous night. She was the more pleased that she had remained absent, as she was told by the governess that Lord Charvington was away in London.

After that merry meal, Lesbia went to change her dress in order to go down to the drawing-room. Agatha and Lena followed to chatter and help, as they did not like to be separated from their visitor. Lesbia's room was on the first floor, near that of the girls, and on the way the three had to pass the door of Lady Charvington's bedroom. It was closed, but as they passed they heard a shriek of alarm, and opening it at once saw one man escaping by the window, and another struggling with Bertha, the ancient maid. Agatha and Lena ran away screaming for help, but Lesbia dashed forward to help the old woman. At that moment the man--who wore a mask--threw Bertha on the ground and ran towards the window. Lesbia caught him before he could fling his leg over the sill, and tore off the mask. Then she uttered a cry of dismay and terror.

"Father!" she shrieked, and dropped down in a dead faint.
