"Fancy being worth more than a hundred pounds!" said Fatty, staring at Dark Queen, who stared back with unwinking blue eyes.

"Could you get Dark Queen out?" asked Daisy, who was longing to hold the beautiful cat. "Is she tame?"

"Oh yes" said Miss Harmer. "They are all tame. We only keep them in cages because they are so valuable. We couldn't let them roam free in case someone stole them."

She took a key from a nail, and unlocked the cage-door. She lifted Dark Queen out, and held her. The beautiful cat rubbed against her, purring in a deep voice. Daisy stroked her, and to her delight the cat jumped into her arms.

"Oh, isn't she friendly?" said Daisy joyfully.

Then there came a great disturbance! Buster suddenly rushed along the path and flung himself on Fatty, barking joyfully. Dark Queen leapt straight out of Daisy's arms, and disappeared into the bushes. Buster, surprised, stared for a moment, and then, with a loud and joyful yelp, plunged after her. There was a terrific scrimmage.

Miss Harmer squealed. Luke's mouth fell open and he looked frightened. All the cats set up a miaowing. Fatty called fiercely:

"Buster! Come here, sir! BUSTER! Do you hear me? COME HERE, SIR!"

But no amount of calling could get Buster away if there was a cat to chase. Miss Harmer ran in despair to the bushes. Only Buster was there, his nose bleeding from a scratch, his tongue hanging out, his eyes very bright and excited.

"Where's Dark Queen?" wailed Miss Harmer. "Oh, this is awful! Puss, puss, puss!"
