And so was grass. I had been hoping that some tableau might include turf, or there might be animal stalls with hay, for you can find almost anything in the Piazza during Carnival, but nothing came even close to being grass.

We soon decided that our cause was hopeless there, and so far neither of us had thought of an alternative to Giorgio's suggestion of San Trovaso, so we set off on foot. The walk warmed us, but we met with no more success. The only grass we located was behind the walls of the rich, and if the murder was to take place on private grounds, we could not hope to intervene. Fulgentio and I abandoned the hunt by mutual consent and set off at a brisk pace, back to San Remo.

We reached the Trau mansion first and he invited me in for a nightcap. I declined because I still had work to do and I knew that he must be up early to attend to his duties in the palace.

Leaving Ca' Trau, I crossed the campo and entered the calle that leads to the back door of Ca' Barbolano. After one house length it branches. The main branch continues with a single, minor jog, leading to the bridge over the Rio San Remo and the accompanying watersteps; the entrance to Number 96 is there, easily accessible from both land and water and well illuminated to attract customers.

I turned to the branch going off to my left, which is dark, narrow, and bends several times before reaching the courtyard gate to Ca' Barbolano, from which it continues somewhat uselessly to the canal. A stray puff of wind blew out my torch.

Torches don't do that. Wind makes them burn brighter. The Word is a simple spell for creating fire-a morally neutral one, according to the Maestro, although the church may not agree with him-but even the Word requires the user to be able to see his target. Fortunately I could just make out a faint glow where the tip was still smoking, and no one could see what I was doing on that moonless, cloud-shrouded night. I transferred the torch to my right hand, made the required gesture with the left, and spoke the Word. Blue fire ran over the charred end and yellow flames followed it.

A voice ahead of me said, "Arghrraw!"

Low on the ground ahead of me, two eyes glowed golden. Holding my torch high, back in my left hand again, I drew my sword and inched closer.

"Arghrraw…"

Venice has several million cats, but they are usually not as loud as that one. Lions and leopards are unknown. So why was I standing around in the cold listening to a cat? It could eat or fight or mate to its heart's content, so far as I cared. I moved forward again.

"Arghrraw…"

Now I could see it better-tail up, back arched. Cats rarely contract rabies, but they are especially vicious when they do. A bite from a rabid cat must be one of the least pleasant ways of going to one's eternal reward, and I did not trust my swordsmanship against feline reflexes.

"And a fine evening to you also, sier Felix," I said. "Sorry to have disturbed you." I backed cautiously away and it did not follow.

The wider calle brought me, of course, to the watersteps and Number 96, whose welcoming lantern still burned, for it was not yet midnight. The land door opens into the waterfront loggia, where half a dozen boatmen sat huddled around a brazier. Their gondolas nodded among the mooring posts outside the arches. Ripples slapped.

Violetta would not be back yet from the musical salon at Ca' Grimini, and she would not return alone anyway, so normally I would have gone right on by, walking to the far end of the gallery and then negotiating the ledge to the narrower calle and Ca' Barbolano. That would have required me to run the gauntlet of the boatmen's foul ribaldry, of course, but anyone who worries about gondoliers' manners should never visit Venice. What made me hesitate was not fear of ridicule but the thought of Alessa. Although she had refused to share information with us over dinner, she had now had many hours to reconsider. Ignoring several boatmen's offers to row me to much better establishments, I opened the door and went in.

The entrance is a cosy parlor, illuminated by numerous lamps and warmed in winter by a toasty fire, mainly for the benefit of skimpily dressed hostesses. The decor is heavy on red and gold and gilt-framed paintings of nudes that never saw the inside of Titian's studio. The air was weighty with wine and perfume, and sounds of drunken revelry were audible beyond the door at the back, which leads through to ground floor rooms for those who are short of either time or money and thus cannot afford to linger. The staircase in the corner leads to the owners' apartments on the piano nobile and then on up to a second commercial area, of higher delights and much higher prices.

Uttering cries of joy, two girls on duty jumped up to greet me. I rewarded them with a polite smile and headed to the stairs, where scar-faced Antonio perched awkwardly on a stool. On my admittedly rare visits to the brothel when it is open for business, I had never seen the chief guard displayed so prominently. Obviously security was tighter than usual at Number 96 and perhaps at every brothel in the city. Word gets around. Because of the temperature, he was stripped down to a shirt and breeches, which made him look even meaner than he does when respectably dressed, while the contrast with his two delectable companions emphasized his nightmare ugliness. He knows me, but he eyed me distrustfully on principle.

"She's still out?" I asked.

Antonio nodded.

"With someone known to you? Not masked, I hope."

"Of course," he growled. "Think I'm stupid? And we don't admit friars."

So many words had gotten around, and perhaps Honeycat would have to hunt outdoors from now on, as the Maestro's quatrain suggested.

"I need to speak with Alessa."

He frowned and then shrugged. Antonio's shrugs create drafts. "She's upstairs. I'll ask." He went, striding two treads at a time.

"You're Violetta's doorman aren't you?" asked the taller of the two seminudes. She advanced predatorily.

"You should try a little variety," the other suggested, starting a flanking maneuver.

"You're much too cute to waste on just her."

"Beware!" I cried, retreating into a corner. "Think what Violetta will do to you if you molest my innocence."

"On, now I have heard everything!"

"Shameless! Who's going to tell her?"

"I'm here on business!" I protested.

"So are we."

I was saved from an unmentionable fate by a blast of cold air from the outer door, wafting in a couple of drunken sailors, masked for Carnival and eager to open negotiations. While the girls were deftly removing the men's masks and boosting their ardor, Antonio came clattering down the stairs and beckoned me. I followed him up to where a second bravo guarded the door to the piano nobile.

Antonio introduced us while he fumbled for the key. "Luigi… Alfeo… Alfeo's all right. A friend." Once inside, he led the way along a dark corridor to Alessa's door, where he paused, as if suddenly uncertain. "She's not herself."

"What way not herself?"

"She's pretty drunk."

"Violetta would murder me."

The big man chuckled. "So she would." He stalked away.

A faint wedge of light showed under the door. As Venice sinks slowly into the mud of the lagoon, its doors and windows-even its walls-forswear right angles in favor of ideas of their own. I tried the handle and went in. Alessa lacks Violetta's flair for artistic arrangement and her apartment is overly cluttered with expensive knickknackery. I picked my way in near darkness through this forest of glass, ceramic, and plaster until I found her in an armchair in her salotto, huddled close to a dying fire and clad in a loose robe that no respectable lady would wear even when alone. Her hair was unbound, dangling everywhere, her face paint messed. Fortunately the single lamp on the mantel shed very little light on her shame, but the reek of wine confirmed what Antonio had told me. First Matteo and now Alessa-Honeycat was doing good things for the vintners of Venice.
