Payne didn’t look worried, which only proved how stupid the man was. Hart could be viciously vindictive, and he never gave up.

“Just tell me one thing,” Mac said. “Why the hell do you want to be Mac Mackenzie?”

Payne’s eyes flickered, and Mac expected any second to learn what a bullet felt like going through his skull.

“Mac has everything,” Payne said. “Talent, friends, family.”

“Samson Payne had that,” Mac pointed out. “Family back in Sheffield. Talent. I’ve seen your work—it’s bloody good. I don’t know about friends. You’ll have to tell me.”

“Samson can’t have art lessons. Samson can’t leave home. Samson can’t do anything but drudge all his life, while soft-handed lords have anything they want. I can do that. I can paint just like him. I’ll do it so well that no one will be able to tell the difference, and then they’ll think he’s the fraud. The aristocrat’s son stooping to steal the work of poor Samson Payne.”

His singsong voice chilled Mac’s blood. “You are all twisted up inside, aren’t you? I would have given you the lessons, Payne. I would have helped you. It was yours for the asking.”

“You would have seen how much better I was than you.”

“Hell, scores of artists are better than I am. I paint what I want and don’t give a damn about contributing to the art world. That’s why I give the bloody paintings to my friends, and they indulge me by hanging them on their walls.”

Payne didn’t appear to be listening. “Get out,” he said.

Mac stilled, calculating the odds of smacking the gun away before Payne could shoot him. Pistol or no, Mac had no intention of diving out of this hansom cab and letting Payne finish the journey to North Audley Street and Isabella.

The pistol barrel was cold on his skin, Payne almost caressing him with it. Mac wondered why he didn’t feel more fear, but maybe rage took care of that.

“If you shoot me, it will make a hell of a lot of noise,” Mac said in a reasonable tone. “And people will have you.”

“They will understand why I had to do it.”

Miss Westlock is right; he’s a complete madman. In Payne’s mind, he would have shot the false Mac, and Isabella would welcome him into her arms for it.

The thought of Isabella waiting for Mac, perhaps in that dressing gown that clung to her body like water, made the berserker in him roar to the surface. Mac knocked his elbow into Payne and ducked as the pistol exploded in his ear. He fought through the ringing in his head, trying to knock Payne away. The hansom spun sideways as the horses bolted at the sound, the driver’s shouts dim in Mac’s deadened hearing.

Mac had no way of knowing what had happened to the damn pistol, but the mad Highlander in him didn’t care. Killing the man with his bare hands would be so much more satisfying.

Payne slithered from Mac’s grasp. As the hansom rocked, the door flew open, and Payne scrambled to the pavement.

“No ye don’t, ye bloody bastard.” Mac leapt after him. He yanked at Payne’s coat, but Payne gave a mighty twist, plunged in front of a cart, and darted into a narrow passage on the other side of the street.

Mac went right after him. Rain poured down, blotting out all light. Mac had no idea where they were, but the streets were rubbish-strewn and narrow, and Payne ran through them with the ease of familiarity. Mac ran fast, faster, pounding through puddles and filth, rain pouring into his face.

Payne kept darting through the maze of passages, the man surprisingly swift on his feet. They crossed a wider street filled with carriages, too damned many for this time of night.

Payne put on a burst of speed, but Mac had plenty of energy to keep up with him. After Payne died, then Mac could rest.

Payne charged into another narrow lane, and Mac sprinted behind him. This passage was dark and noisome, with the skittering of rats to go with it.

Rats in a hole, Mac thought grimly. Payne kept good company.

He reached the end of the passage, a blank wall with no doors. And no Payne.

Damn the man, he’d doubled back. Mac turned to run after him.

A light flashed, followed by a horrible noise that penetrated even his deafened ears. After two steps, Mac’s feet no longer worked. His knees buckled against his will, and the pavement rushed up to meet him.

What the hell? What the hell? Mac put his hands on the cold ground, trying to push himself up, but his breath was gone. A large wet patch stained his side—he must have fallen into a puddle. He’d let Payne face Bellamy for that. The former pugilist enraged about Mac’s clothes was a fearsome sight.

Payne’s footsteps echoed as the man walked down the passage to Mac. Mac smelled the acrid stench of a pistol that had just been fired. He opened his mouth to shout, but his lungs wouldn’t work. For some reason, he could barely breathe.

And then pain came. Terrible, blossoming pain, spreading from his side up into his arm and down his leg. Damn it to hell.

Payne, silhouetted by the brighter street beyond the passage, holstered his pistol, scooped Mac up by his armpits, and began to drag him away.

“I don’t know where he is,” Inspector Fellows repeated in irritation. “We hadn’t found Payne by three, and Lord Mac said he’d go home to tell you. He got into a hansom cab, and that was the last I saw of him.”

Isabella rubbed her hands and paced the drawing room. She’d barely been able to stay still while Evans dressed her, but she reasoned she couldn’t rush downstairs in her dressing gown. She was a proper Englishwoman, an earl’s daughter, and an aristocrat’s wife. She could not appear in undress in front of visitors. Both Fellows and Cameron had answered her frantic summons, arriving very quickly after her messages.
