"No, no! Let's feel our way! I'm sure we can," urged Toby. "Come on!

It'll be fun. Shut the door!"

The spirit of adventure seized upon Bunny. He let the door swing closed and caught her hand again.

Toby's delighted chuckle told him that she had fully recovered her equilibrium. Her fingers twined closely about his own.

"Now we shall have some fun!" she said.

They went forward together for a few yards in total darkness. Then, from somewhere high above them a faint light filtered through.

"That's on the stairs," said Bunny. "One of those window-slits through which in the old hospitable days all comers were potted at. Look out how you go!"

The words were scarcely uttered when they both kicked against the lowest stair and blundered forward. A squeal of laughter came from Toby. Bunny said "d.a.m.n!" with much heartiness and then laughed also.

"I knew it would be fun," said Toby. "Are you hurt?"

He raised her with a strong young arm. "No, I'm all right. Are you?"

"Yes. I'm loving it. What happens next? Do the stairs wind round and round till we get to the top?"

"Yes. There are about six hundred of 'em. Feel equal to it?"

"Equal to anything," said Toby promptly. "Let me go first!"

"Why don't I go and get a light?" said Bunny.

"Because you're not to. Because it's heaps more fun without. Besides, there's lots of light up there. Now then? Are you ready? Come on! Let's go!"

Indomitable resolution sounded in Toby's voice. She drew herself free from Bunny's hold, and began to mount.

"You know it's haunted, don't you?" said Bunny cheerily. "A beautiful lady was once captured and imprisoned in this turret in the dear old days when everyone did those things. She had to choose between throwing herself from the battlements and marrying her wicked captor--an ancestor of Charlie's, by the way. She did the latter and then died of a broken heart. They always did, you know. Her poor little ghost has wandered up and down this stair ever since."

"Idiot!" said Toby tersely.

"Who?" said Bunny. "And why?"

"The woman. Why didn't she throw herself over? It would have been much easier."

"Perhaps she didn't find it so," said Bunny. "And she'd doubtless have done the haunting stunt even if she had."

"Well, then, why didn't she marry the brute and--and--give him h.e.l.l?"

said Toby tensely.

Bunny uttered a shout of laughter that echoed and re-echoed up and down the winding stair.

"Is that what you would have done?"

"I'd have done one or the other," said Toby.

"By Jove, how bloodthirsty you sound!" e.j.a.c.u.l.a.t.ed Bunny. "Are you in earnest by any chance?"

"Yes, I am in earnest." There was a note of bitter challenge in Toby's reply. "If a woman hasn't the s.p.u.n.k to defend herself, she's better dead."

"I agree with you there," said Bunny with decision. "But I don't know how you come to know it."

"Oh, I know a lot of things," said Toby's voice in the darkness, and this time it sounded oddly cold and desolate as if the stone walls around them had somehow deadened it.

He put out a hand and touched her, for she seemed in some fashion to have withdrawn from him, to have become remote as the echoes about them.

"There are heaps of things you don't know anyway," he said. "You're only a kid after all."

"Think so?" said Toby.

She evaded his hand, flitting up before him towards that grim slit in the wall through which the dim half-light of the summer night vaguely entered. Her light figure became visible to him as she reached it. There came to him a swift memory of the b.u.t.terfly-beauty that had so astounded him earlier in the evening.

"No, I don't," he said. "You're past that stage. What on earth has Maud been doing to you? Do you know when you first came into the drawing-room tonight I hardly knew you?"

Toby's light laugh came back to him. She was like a white b.u.t.terfly flitting before him in the twilight. "I wondered what you'd say. I've given up jumping rosebushes, and I'm learning to be respectable. It's rather fun sometimes. Maud is very good to me--and I love Jake, don't you?"

"Yes, he's a brick; always was," said Bunny enthusiastically. "I'd back him every time. But, I say. Don't get too respectable, will you? Somehow it doesn't suit you."

Again he heard her laugh in the darkness--a quick, rather breathless laugh. "I don't think I'll ever be that," she said. "Do you?"

"I don't know," said Bunny. "But you looked scared to death when you came in--as if you were mounted on a horse that was much too high for you. I believe you were afraid of that old daddy of yours."

"I am rather," said Toby. "You see, I don't know him very well. And I'm not sure he likes me."

"Of course he likes you," said Bunny.

"Why? I don't know why he should."

"Everyone does," said Bunny, with a.s.surance.

"Don't be silly!" said Toby.

They were past the slit in the wall, and were winding upwards now towards another. Bunny postponed argument, finding he needed all his breath for the climb. The steps had become narrower and more steeply spiral than before. His companion mounted so swiftly that he found it difficult to keep close to her. The ascent seemed endless.

Again they pa.s.sed a window-slit, and Bunny suddenly awoke to the fact that the flying figure in front was trying to out-distance him. It came to him in a flash of intuition. She was daring him, she was fooling him.

Some imp of mischief had entered into her. She was luring him to pursuit; and like the whirling of a torch in a dark place, the knowledge first dazzled, and then drew him. All his pulses beat in a swift crescendo.

There was a considerable mixture of Irish deviltry in Bunny Brian's veins, and anything in the nature of a challenge fired him. He uttered a wild whoop that filled the eerie place with fearful echoes, and gave chase.

It was the maddest race he had ever run. Toby fled before him like the wind, up and up, round and round the winding stair, fleet-footed, almost as though on wings, leaving him behind. He followed, fiercely determined, putting forth his utmost strength, sometimes stumbling on the uneven stairs, yet always leaping onward, urged to wilder effort by the b.u.t.terfly elusiveness of his quarry. Once he actually had her within his reach, and then he stumbled and she was gone. He heard her maddening laughter as she fled.

The ascent seemed endless. His heart was pumping, but he would not slacken. She should never triumph over him, this mocking imp, this b.u.t.terfly-girl, who from the first had held him with a fascination he could not fathom. He would make her pay for her audacity. He would teach her that he was more than a mere b.u.t.t for her drollery. He would show her--

A door suddenly banged high above him. He realized that she had reached the top of the turret and burst out upon the ramparts. A very curious sensation went through him. It was almost a feeling of fear. She was such a wild little creature, and her mood was at its maddest. The chill of the place seemed to wrap him round. He felt as if icy fingers had clutched his heart.

It was all a joke of course--only a joke! But jokes sometimes ended disastrously, and Toby--Toby was not an ordinary person. She was either a featherbrain or a genius. He did not know which. Perhaps there was no very clear dividing line between the two. She was certainly extraordinary. He wished he had not accepted her challenge. If he had refused to follow, she would soon have abandoned her absurd flight through the darkness.
