That laugh again, hurt and hateful, with more experience than it should hold. “Please, don’t. You are too good at causing damage to have any skill at repairing it.” She added, “I don’t want you in my life. I will deal with him.”

“He won’t see you,” he said. “That is part of our bargain.”

“How dare you negotiate with him on my behalf?”

He shook his head and spoke the truth, tired of holding it back. “He came to me, Lavinia. And as much as you would like to believe otherwise, I couldn’t let him hurt you. I will never let him hurt you.”

The words might have had an impact, but he would never know, because at that precise moment, as they faded into the air around him, there was a loud thump from the opposite side of the large painting that hung on one wall of his office, and a dreadful knowledge settled deep and unpleasant in his gut. He knew what was on the other side of that painting, knew where it led.

Knew, too, with utter certainty, who was standing mere inches away from his office.

Lifting a hand to keep his sister from saying any more, he rounded his desk and grasped one edge of the massive gilt frame, giving the enormous oil painting a heavy yank, opening the secret entrance and revealing a wide-eyed Philippa Marbury, who tumbled out of the passageway beyond, barely catching herself on a nearby table before straightening and facing the occupants of the room.

She did not miss a beat, righting her spectacles and moving past him, into the office, to say, “Hello, Lady Dunblade,” before turning a cool blue gaze on him, triumphantly setting a pair of ivory dice on the edge of his great black desk, and adding, “You, sir, are a liar and a cheat. And I will not be ordered about like a prize hound.”

There was a moment of collective stunned silence, during which Lavinia’s jaw dropped and Cross wondered how precisely his calm, collected life had gone spiraling so completely out of control.

His Lavinia was Lavinia, Baroness Dunblade. A lady.

It was fascinating how simply society rendered invisible those who had suffered unfortunate circumstances. Lady Dunblade might require a cane to aid in her unavoidable limp, but now, as she stood on one side of Mr. Cross’s cluttered office, Pippa wondered how the lady could escape notice. Injury aside, she was tall and beautiful, with lovely red hair and brown eyes that Pippa could not help but admire.

Apparently, she was not the only one to admire those eyes. Apparently, Mr. Cross thought they were worthy of admiration as well. Pippa shouldn’t be surprised. After all, Mr. Cross was a notorious rogue—even if he’d never even hinted at any kind of roguish behavior with Pippa—and Lady Dunblade so often went beyond notice, that she could easily come and go from The Fallen Angel without causing scandal.

But scandal she was, apparently, as she was here, standing in Cross’s office, straight and proud, like a Grecian queen.

And why shouldn’t she stand proud? She’d apparently caught the attention of one of the most powerful men in London.

Pippa would be quite proud herself if she had done the same.

She resisted the thought and the thread of newly, unpleasantly, defined emotion that coursed through her with it, and turned to close the door to the secret passageway. She should have guessed that he had chosen a room with a passage leading to his office—he was not the kind of man who relied on coincidence.

And he was likely not the kind of man to be happy that she’d just tumbled through the wall and into his office . . . and if what she had overheard was to be believed . . . into a very private conversation.

I will never let him hurt you.

Even through the wall, she’d heard the fierceness in his tone. The commitment. Even through the wall, she’d felt the words like a blow. He clearly cared for the lady. Cared for her enough to leave Pippa in a locked room and go to her.

She shouldn’t be upset. After all, theirs was a partnership, not a relationship.

This was no time for jealousy. No place for it. There was no jealousy in science.

Except, apparently, there was.

She shouldn’t be jealous. She should be angry. He’d defiled their agreement by cheating her with weighted dice and wicked lies. Yes. In fact, that was why she had come here furious, was it not? If she was upset, it should be for that reason, and nothing else.

Certainly not because he’d left her to come for this lady.

She should not be upset about that at all.

And yet, that seemed to be precisely the reason for her upset.

Curious, that.

Once the passageway was closed, she spun back to face Mr. Cross and Lady Dunblade. Taking in the fury on his face and the shock on hers, Pippa said the first thing that came to mind. “I am sorry to interrupt.”

There was a beat, as they heard the words, before they both spoke.

“We are through,” said the lady, shoulders squaring as she seemed to remember where she was, backing toward the door. “I am leaving.”

“What in hell are you doing inside that passageway? I told you not to move from that room,” said Mr. Cross at the same time.

“You left me in a locked room and expected me not to attempt to escape?” Pippa said, unable to keep the frustration from her tone.

“I expect you to keep yourself safe from harm.”

Her eyes went wide. “What harm could possibly come to me?”

“In a dark, secret passageway in a gaming hell? You’re right. No harm indeed.”

She took a step back. “Sarcasm does not become you, Mr. Cross.”

He shook his head in frustration and turned to Lady Dunblade, who had reached the door. “You are not leaving.”
