MY FATHER had been an assassin for so long that the men he had killed were like leaves on a willow tree, too many to count. Because he possessed a skill that few men had and claimed the power of invisibility, he could slip into a room as a shadow might, dispatching his enemy before his victim was even aware that a window had been opened or a door had closed.

To my sorrow, my brother followed our father’s path as soon as he was old enough to become a disciple of vengeance. Amram was dangerously susceptible to their violent ways, for in his purity he saw the world as either good or evil with no twilight space in between. I often spied them huddled together, my father speaking in my brother’s ear, teaching him the rules of murder. One day as I gathered Amram’s tunics and cloak to wash at the well I found a dagger, already rippled with a line of crimson. I would have wept had I been able, but I had forsaken tears. I would not drown another as I had drowned my own mother, from the inside out.

Still, I went in search of my brother, finding him in the market with his friends. Women alone were not often seen among the men who came to these narrow passageways; those who had no choice but to go out unaccompanied rushed to the Street of the Bakers or to the stalls that offered pottery and jugs made from Jerusalem clay, then, just as quickly, rushed home. I wore a veil and my cloak clasped tightly. There were zonnoth in the market, women who sold themselves for men’s pleasure and did not cover their arms or their hair. One mocked me as I ran past, her sullen face breaking into a grin when she spied me dashing through the alleyway. You think you’re any different than we are? she called. You’re only a woman, as we are.

I pulled my brother away from his friends so that we might stand beneath a flame tree. The red flowers gave off the scent of fire, and I thought this was an omen, that my brother would know fire. I worried over what would happen to him when night came and the Sicarii gathered under cedars where they made their plans. I begged him to renounce the violent ways he’d taken up, but my brother, young as he was, burned for justice and a new order where all men were equal.

“I can’t reconsider my faith, Yaya.”

“Then consider your life” was my answer.

To tease me, Amram clucked like a chicken, strutting, his lean, strong body hunched over as he flapped imaginary wings. “Do you want me to stay home in the henhouse, where you can lock me inside and make sure I’m safe?”

I laughed despite my fears. My brother was brave and beautiful. No wonder my father favored him. His hair was golden, his eyes dark but flecked with light. I saw now that the child I had once mothered had become a man, one who was pure in his intentions. I could do little more than object to the path that he chose. Still I was determined to act on his behalf. When my brother rejoined his friends, I went on through the market, making my way deep within the twisting streets, at last turning in to an alley that was cobbled with dusty, dun-colored bricks. I’d heard it was possible to buy good fortune nearby. There was a mysterious shop spoken about in whispers by the neighborhood women. They usually stopped their discussion when I came near, but I’d been curious and had overheard that if a person followed the scrawled image of an eye inside a circle she would be led to a place of medicines and spells. I took the path of the eye until I came to the house of keshaphim, the breed of magic practiced by women, always pursued in secret.

When I knocked on the door, an old woman came to study me. Annoyed by my presence, she asked why I’d come. As soon as I hesitated, she began to close the door against me, grumbling.

“I don’t have time for someone who doesn’t know what she wants,” she muttered.

“Protection for my brother,” I managed to say, too unnerved to reveal any more.

At the Temple there was the magic of the priests, holy men who were anointed by prayer, chosen to give sacrifices and attempt miracles and perform exorcisms, driving out the evil that can often possess men. In the streets there was the magic of the minim, who were looked down upon by the priests, called charlatans and impostors by some, yet who were still respected by many. Houses of keshaphim, however, were considered to engage in the foulest sort of magic, women’s work, evil, vengeful, practiced by those who were denounced as witches. But the min who performed curses and spells would have never spoken to a girl such as I if I had no silver to hand over and no father or brother to recommend me. And had I gone to the priests for an amulet, they would have denied me, for I was the daughter of one who opposed them. Even I knew I didn’t deserve their favor.

The room behind the old woman was unlit, but I glimpsed herbs and plants draped from the ceiling on lengths of rope. I recognized rue and myrtle and the dried yellow apples of the mandrake, what is called yavrucha, an herb that is both aphrodisiac and antidemonic in nature, poisonous and powerful. I thought I heard the sound of a goat, a pet witches are said to have, from inside the dim chamber.
