Green glass beads with glinting spacers tangled in the four-color braid on the neck of her finely woven tunic. Adept boudoir maids must have helped to arrange the circle of dark curls around her face and to position the gold net that pegged them in place. If she was showing a lot of leg below the tunic, that was because it was such a short tunic. She handled her smooth emerald stole with unflustered ease when it slid off her shoulders. She looked as if she assumed she could handle me as easily.

There was one problem. My ideal client, assuming Helena Justina permitted me to assist such a person nowadays, would be a pert widow aged somewhere between seventeen and twenty. I placed this little gem in a far less dangerous bracket. She was only five or six.

I leaned on the balcony newel post, a rotting timber the landlord should have replaced years ago. When I spoke my voice sounded weary even to me. “Hello, princess. Can’t you find the door porter to let you in?” She stared at me scornfully, aware that grimy plebeian apartments did not possess slaves to welcome visitors. “When your family tutor starts to teach you about rhetoric, you will discover that that was a feeble attempt at irony. Can I help you?”

“I was told an informer lives here.” Her accent said she was upper class. I had worked that out. I tried not to let it prejudice me. Well, not too much. “If you are Falco, I want to consult you.” It came out clear and surprisingly assured. Chin up and self-confident, the prospective client had the bright address of a star trapeze artiste. She knew what she wanted and expected to be listened to.

“Sorry, I am not available for hire.” Still upset by my visit to Maia, I took a sterner line than I should have done.

The client tried to win me over. She hung her head and looked down at her toes pathetically. She was accustomed to wheedling sweetmeats out of somebody. Big brown eyes begged for favors, confident of receiving what she asked. I simply gave her the hard stare of a man who had returned from imparting tragic news to people who then decided to blame him for the tragedy.
