The first pages of The Secret Word, for your reading pleasure.

If the lady had let go of her reticule, Christopher Satterthwaite might never have met her. A sensible person would have let Dasher Baggins take off with the scrap of lace and whatever was inside it. A sensible person would not have made a fuss in a street like this, where the law-abiding denizens knew better than to stand in the way of a villain, and where the villains would swarm like sharks at the hint of a victim.
A sensible person would not be in this street to begin with, not looking like a sweet and expensive confection in laces and silks, and certainly not screeching at the top of her voice, hanging on to her reticule for dear life, and beating the thief around his ears with her parasol.
Chris, who was mostly law-abiding, knew better than to interfere, but he couldn’t help himself. He closed the distance between himself and the little tableaux—outraged maiden beats off cheeky rascal—in a fast walk, designed not to attract more attention than he could help.
“Let go, Dash,” he told the boy. “She’s with me.”
“Aw, Fingers,” Dasher whined. “Don’t know what she’s got in there, but it must be worf somefing, way she hangs on.”
“My mother’s miniature, and you shan’t have it,” said the lady, who held her parasol ready but had at least stopped using it to beat Dash with. The poor lad should stick to mud larking. He was not a good thief.
“Get lost, Dash,” Chris told him, and flipped him a farthing.
Dash let go of the reticule to catch the coin, and then demonstrated the reason for his nickname, dashing off through the crowd.
“You should have held him while I called a constable,” proclaimed the lady.
“I don’t know if you’ve noticed, Miss, but constables don’t come down here,” Chris replied. Up until now, he had been speaking street cant, or just far enough above it that Dash was comfortable, but now he changed accent and vocabulary to talk to the lady in a way she would respond to. A cut above hers, in fact, for her vowels were not quite as nasal nor her consonants as crisp as Chris’s grandfather’s. “It is too dangerous,” he elaborated. “Too many villains.”
The lady huffed with displeasure, setting the ruffles on her bodice quivering. “One would think there would be fewer villains if the constables did come down here.”
“Or fewer constables,” Chris argued.
She blinked at him as she absorbed the point, then huffed again. “I should not be here. I must have got turned around. Can you direct me to Meadow Court?”
“You do not want to go to Meadow Court,” Chris told her. If Bleak Street did not eat her up and spit her out, Meadow Court would swallow her whole. And there’d be no spitting her out, either.
The lady’s huff was more of a snort. “I decidedly do, sir,” she insisted.
“”Shall I tell you what will happen if you make it as far as Meadow Court?” Chris asked. It was a rhetorical question. “First, you shall be robbed of everything you have, including the clothes you stand up in. Then one of two things will happen to your naked person, depending on whether you fall into the hands of an organised gang or just a mob of the hopeless.”
He fell silent and watched to see how she would react. Not as expected. Her eyes widened—they were a lovely shade of blue. Her cheeks paled. So far, quite predictable. But then she pressed her coral-pink lips together and gave a sharp nod, as if she had presented herself with a compelling argument.
“Nonetheless, sir, I have an errand in Meadow Court that will not wait.”
“An organised mob will sell you to a brothel, where they will auction your virginity then put you to work servicing their clients until you drink yourself to death or die of an unspeakable disease,” Chris told her.
She paled still further. Not such an innocent that she did not know what he meant, then. “Nonetheless,” she repeated, but her voice shook.
“A mob will not bother with the brothel,” he continued, determined to make her change her mind. “And you will die of what they do to you.” He could not bear to describe it further, did not even what to think of her intimately assaulted by one brute after another, screaming for help that never came, dying in agony of body and soul.
“Nonetheless.” It was little more than a whisper, and she was so pale he thought she might faint.
“Why?” he asked. “What is so important that you are willing to die for it—die, most likely, without accomplishing it?”
She narrowed her eyes at him, considering. “I have no reason to believe you, sir,” she said. “All I know about you is that you belong so well to this street, in which you say everyone is a villain, that thieves do your bidding. Ama— My friend would not have written asking me to come to Meadow Square if it was as dangerous as you say.”
“I said the place had too many villains,” Chris pointed out. “Not that I am one. As it happens, I am not, but you have a point. We do not know one another. Please allow me to introduce myself.” He bowed. “I am Christopher Satterthwaite. And you are…?”
She curtseyed in response to his bow, “Clementine Perkins.”
“Miss Perkins, I cannot know what your friend had in mind—you are sure it was in her hand? But have you considered she might have been threatened or tricked.”
“Why?” Miss Perkins’ asked. “Why would someone bother?”
Chris had recognised her name and he knew the answer to that. Perkins was a common enough name, but combined with Clementine? She was the coal heiress, beyond a doubt, and her father was one of the richest mine owners in the United Kingdom.
Something about the way Miss Perkins was not quite meeting his eyes hinted that she, too, knew the most likely reason criminals would attack her.
“Option three,” he replied. “You must have thought of it yourself, Miss Perkins. I would have mentioned it before, if we had been introduced earlier. Option three is ransom, though that doesn’t mean that other criminal groups will not prefer option one or option two.”
Oh-oh. He had grown up in places like this, and knew better than to allow her undoubted charms to keep him from scanning the street, looking for danger. But despite that, he’d been distracted.
He should have run as soon as the first of the three men arrived at the mouth of the alley that led to Meadow Court. He would be hard pushed to make it out of Bleak Street now that three of them were gathered.. He certainly could not manage it with Miss Perkins in tow.
There was really only one option. “Miss Perkins, there is someone I would like you to meet. Step this way, please.” He offered her his arm.
She put both of hers behind her back. “I do not think so, Mr Satterthwaite. If that is your name. You keep telling me not to trust anyone and then insisting I can trust you.”
They were coming. All three of the Brown brothers, and behind them, the rest of the gang. Cautiously, for this was Ramping Billy O’Hara’s street, and he’d not take kindly to the Brown brothers trespassing on his territory.
Chris sighed and pointed. “See those men, Miss Perkins?”
She caught sight of Basher Brown’s grin and let out a squeak of dismay. Wise girl! She moved closer to Chris.
“This way,” Chris told her. He took her hand, and led her at a run up Bleak Street. To her credit, she ran like a deer, but the Brown gang was in full pursuit behind, and everyone else was turning away, pretending that they saw nothing.
