He gave her the money, and accepted the steaming coffee in return. He stood on the pavement, drinking slowly and thinking how he could approach the police when he reached the Edgware Road station. They would resent his interference, even if the case threatened to be so ugly they would be glad to pass the blame on to someone else. He knew how he had felt when he was in charge of Bow Street. Good or bad, he wanted to handle cases himself, not have his judgment overridden by senior officers who knew less of the area, of the details of the evidence, and who had not even met the people concerned, let alone questioned them, seen where they lived, who they cared for, loved, feared, or hated.

The cases he had handled so far in Special Branch were largely preventative: matters of finding men likely to incite violence and stir up the cold, hungry, and impoverished into riot. Occasionally he had been involved in the search for an anarchist or potential bomber. The Special Branch had been formed originally to combat the Irish Problem, and had had a certain degree of success, at least in keeping violence under control. Now its remit was against any threat to the security of the country, so possibly the fall of a major government figure could be scraped into that category.

He finished the coffee and handed the mug back to the woman, thanking her and continuing along the pavement. He took the last few yards at a run as he saw an empty hansom stop at the intersection, and he hailed the driver.

At the Edgware Road station an Inspector Talbot was in charge of the case and received Pitt in his office with barely concealed impatience. He was a man of middle height, lean as a whippet, with sad, slightly faded blue eyes. He stood behind his desk, piled with neatly handwritten reports, and stared at Pitt, waiting for him to speak.

“Thomas Pitt from Special Branch,” Pitt introduced himself, offering his card to prove his identity.

Talbot’s face tightened, but he waved a hand for Pitt to sit down in one of the rigid, hard-backed chairs. “It’s a clean case,” Talbot said flatly. “The evidence is pretty hard to misunderstand. The woman was found with the body, trying to move it. It was her gun that shot him, and it was in the barrow beside the body. Thanks to someone’s quick thought, we got her in the act.” The expression in his face was a challenge, daring Pitt to contradict such blatant facts.

“Whose honesty?” Pitt asked, but his stomach knotted up with foreknowledge of a kind of hopelessness already. This was going to be simple, ordinary and ugly, and as Talbot said, there was no way of evading it.

“Don’t know,” Talbot replied. “Someone raised the alarm. Heard the shots, they said.”

“Raised the alarm how?” Pitt asked, a tiny prickle of curiosity awakened in him.

“Telephone,” Talbot answered, catching Pitt’s meaning instantly. “Narrows it down a bit, doesn’t it? Before you ask, we don’t know who. Wouldn’t give a name, and apart from that, the caller was so alarmed the voice was hoarse-and so up and down the operator couldn’t even say for sure whether it was a man or a woman.”

“So the caller was close enough to be certain it was shots,” Pitt concluded immediately. “How many houses have telephones within a hundred yards of Eden Lodge?”

Talbot pulled his mouth into a grimace. “Quite a few. Within a hundred and fifty yards, then, probably fifteen or twenty. It’s a very nice area, lot of money. We’ll try asking, of course, but the fact the caller didn’t give a name means he or she wants to keep well out of it.” He shrugged. “Pity. Might have seen something, but I suppose more likely they didn’t. Body was found in the garden, well concealed by shrubbery, all leaves still on the trees, barely beginning to turn color. Laurels and stuff on the ground, evergreens.”

“But you found it straightaway,” Pitt pointed out.

“Could hardly miss it,” Talbot said ruefully. “She was standing there in a long white dress, with the dead man draped over a wheelbarrow in front of her, like she’d just dropped the handles when she heard the constable coming.”

Pitt tried to picture it in his imagination, the dense blackness of the garden in the middle of the night, the crowding leaves, the damp earth, a woman in an evening gown with a corpse in a wheelbarrow.

“There’s nothing for you to do,” Talbot interrupted.

“Possibly.” Pitt refused to be dismissed. “You said there was a gun?”

“Yes. She admitted it was her gun. Had more sense than to try and deny it. Handsome thing, engraved handle. Still warm, and smelled of powder. There’s no doubt it was what killed him.”

“Could it have been an accident?” Pitt asked without any real hope.

Talbot gave a little grunt. “At twenty yards, possibly, but he was shot within a few feet. And what would a woman like that be doing out in the garden with a gun at three in the morning, except on purpose?”

“Was he shot outside?” Pitt asked quickly. Was Talbot making assumptions, possibly wrong?

Talbot smiled very slightly, only a twitch of the lips. “Either that or he was left lying outside for some time afterwards; there was blood on the ground. And none inside, by the way.” His expression tightened, his eyes bright and pale. “Takes a lot of explaining, doesn’t it?”

Pitt said nothing. What on earth did Narraway expect him to do? If Ryerson’s mistress had shot this man, there was no reason why Special Branch should even think of protecting her, much less lie to do it.

“Who was he?” he said aloud.

Talbot leaned back against the wall. “I was wondering when you’d ask that. Edwin Lovat, ex-army officer and minor diplomat with an apparently good record behind him, and until last night, a promising future ahead. Good family, no enemies that we’ve found so far, no debts that we know of yet.” He stopped, waiting for Pitt to ask the next question.

Pitt concealed his irritation. “So why should this Egyptian woman shoot him, in or out of her house? I assume there was no question of his trying to break in?”

Talbot’s eyebrows shot up, wrinkling his forehead. “Why on earth should he do that?”

“I’ve no idea,” Pitt replied tersely. “Why should she be outside in the garden with a gun? None of it makes any sense!”

“Oh, yes it does!” Talbot retorted fiercely, sitting forward and putting his elbows on the desk. “He served with the army in Egypt. Alexandria, to be precise. Which is where she comes from. Who knows what goes on in the minds of women there? They’re not like white women, you know. But she’s definitely moved up a bit now. She’s the mistress of a cabinet minister, Member of Parliament for a Manchester constituency, where all the trouble is over cotton at the moment. She’s not got time for the likes of an ex-soldier who’s only on the bottom rung of the diplomatic ladder. I daresay he was less keen in taking no for an answer, and she didn’t want him interfering in her new affair and upsetting Mr. Ryerson with tales of her past.”

“Any evidence of that?” Pitt asked. He was angry, and he wanted to prove Talbot prejudiced and inaccurate, but he could not dislike him totally; in fact, he could not seriously dislike him at all. The man was faced with a task in which he could not satisfy his superiors and still keep any kind of honor. Neither would he keep the confidence of the men he commanded, and with whom he would have to work for months and years after this affair was over. What would Pitt have done in the same circumstances? He honestly did not know. He would have been angry as well, casting around for answers, his thoughts leaping ahead of facts.

“Of course there isn’t!” Talbot responded. “But I’ll lay you a pound to a penny that if Special Branch, or someone like them, doesn’t charge in and prevent me, I will have such evidence in a day or two. The crime’s only four hours old!”

Pitt knew he was being unfair.
