Martha couldn't help but notice that Rory looked slightly nervous as they neared the city. Even a mile away, he was already falling into place behind her.

"What's wrong?" she asked, knowing that he would probably spot any danger long before her.

"It's nothing," he said. "Don't worry."

"Give me one good reason why I should believe any of that," Martha shot back.

Rory sighed. "Little villages and big cities play by different rules. I've only been in little villages since..." He shook himself. "I like to know what to expect. That's all."

Martha nodded. "Yeah, I've been in a few; Paris, Barcelona, and Rome."

"The city Barcelona or the planet Barcelona?"

"The city. Anyway, larger cities don't have a single enforcer. The Master pays a lot more attention to them, so they have a whole police force. The entire police force will be carefully monitored and loyal only to the Master. There is also a regiment of Toclofane about. The perception filter keeps the Toclofane from noticing me, and works most of the time with the police force. You'll have to figure something out for yourself."

"Is there anywhere that isn't closely monitored?" Rory asked.

"Religious centers. I believe the reasoning is that people are easier to keep in check if they can still worship. They would likely revolt if their religion was compromised, and the Master needs manpower. Hospitals are also relatively free, but the police force keeps track of who goes in. Transport by ship, train, or plane in and out of the city is nearly impossible for people who haven't been directly brainwashed."

Rory considered this carefully. "Given that Gregorio gave us the rosary, I'd be willing to bet that Favianna is a nun."

Martha gave him a strange look. "Just because she has a rosary, that doesn't mean she's a nun."

"Well, no," Rory agreed. "However, we're looking for a woman who is related to Gregorio, significantly older, and shares the surname. Probably a much older sister who joined a convent."

"First, when did you become Sherlock Holmes? Second, why couldn't Favianna be Gregorio's aunt or wife or something."

"First, I spend too much time thinking. Also, I speak Italian. I don't know if you noticed, but Arduino talked. A lot. Among the things he talked about were his wishes that Gregorio would find a nice girl and settle down. He also mentioned that his wife was an only child and his sister, his only sibling, died giving birth to her second child, Gregorio. Since the mysterious S. F. sent a letter that I'm certain was written fairly recently, given that the Master only showed up less than two years ago, it can be safely assumed that Favianna is still alive. Or at least, she was alive after Arduino's sister had died. Therefore, the only possible relation, and it is a relation if he has her rosary, is sister.

"Then there's the rosary. Presumably, it was given to Gregorio as a means to remember his sister, since it has her name on it. If it is being as a means to remember her, than religion must be very important to her. So, and older, unmarried woman who considers religion to be important above all else. It has to be a nun."

"I'm still not seeing where you got older and unmarried from," Martha said.

"Well, Arduino didn't really stop talking about his family. He would have mentioned it if he had another nephew. As for older, she is close enough to S. F., who outright said that she was an old woman, that S. F. would try to contact her after her death. Of course, she could just be a beloved granddaughter, but once again, Arduino runs his mouth. He didn't stop talking about his sister's pregnancy with Gregorio, but he never once mentioned her first pregnancy. This implies that the first child was born without any trouble. Complications in pregnancy are more likely to arise in older women, indicating a fairly significant length of time between Favianna's birth and Gregorio's. Does that answer your questions?"

Martha considered it. "I suppose so. What can you deduce about our mysterious S.F., Mr. Holmes?"

"Absolutely nothing," Rory replied promptly. "My last name isn't Holmes, by the way."

"What is it, then?" Martha asked, realizing for the first time that she didn't actually know.

Rory paused. "You know, I'm not entirely sure. See, it could be one of two names, and after I married, I was never quite certain which name was my last name."

"So pick one," Martha said.

"It's not that simple," Rory answered. "But if I have to pick, let's go with Ianaurius. It's a good, Roman name. Obviously, I just chose it now, but I think it'll do."

"Rory Ianaurius," Martha said. "I think it works."

"Now," Rory announced. "On to business." He took the Cyllenian dagger off his belt and handed it to Martha, along with the map and the letter to Favianna. "We should stick together, but just in case something happens, Favianna should be at the Calvierri House. It used to be owned by the Calvierri family, those fish-vampires I told you about, but it was turned into a convent after the family's death. For some reason, just about everyone knows it as the Calvierri House. I think it has something to do with the legend surrounding it. If we get separated, wait for me there. If I don't show in four hours, I'm probably dead. Don't worry about me and just keep going. Got it?"

Martha nodded. "Stay away from the alleyways. That's where people expect to find trouble makers. Don't bother with stealth; looking like you have something to hide can get you killed. Also, in places like this, there are usually feuds between different groups of workers. Don't get involved. We can't afford to take sides."

"I'll just follow your lead, then." Rory had what could have been called a grin on his face, if Martha hadn't learned to see the darkness underneath it. He gestured grandly, something Martha assumed he did to hide his nervousness. "Lead on, Miss Martha Jones."

She obliged. The pair ventured into the city under cover of darkness. There were armed patrols everywhere. Martha's perception filter kept her safe, and Rory seemed to have an uncanny ability to know where people wouldn't be looking. She suspected that any perception filter would have been redundant where he was concerned.

They had to go slowly so Rory could stay hidden, and thus they reached the front gate of the Calvierri House, a grandiose door with a three-tiered arch, day was breaking. The gate itself was locked with a chain and massive padlock. Martha picked the lock with practiced ease, and silently thanked Leo for stealing her toys as a child and her parents for installing a lock on his door.

Rory and Martha slipped through the gate and into the shadows of the courtyard.

Suddenly, they both realized that neither of them knew what to do once they got there. An awkward silence descended for a few moments.

"So," Rory said. "Now what?"

A flash of inspiration hit Martha. "We try the domestic approach." With that, she strode confidently up to the door and knocked on it. No one answered. She pocketed her perception filter and tried again. This time, she heard movement from inside.

"The domestic approach seems like a good way to get killed," Rory noted, sounding somewhere between amused and irritated.

"You should make a note of it," Martha replied playfully. Rory just rolled his eyes.

The door was opened by a young woman in a nun's habit. Her eyes widened when she saw Martha, and nearly bugged out of her head when she saw Rory, who greeted her politely.

After a few words, the nun beckoned them in. Inside the doors was what Martha assumed to be an antechamber, but it was as large as the lobby of a three-star hotel. The floor was covered in pallets, most of them occupied by the injured or sick.

"Why are so many people not in the hospital?" Rory asked.

"These people probably weren't the strongest workers to start with. If someone isn't deemed useful, they aren't allowed into the hospitals," Martha replied, deceptively calm.

The nun who had greeted them turned down a side hallway, again beckoning them to follow.

"Where are we going?" Martha asked. Rory shrugged. He translated her question. At the nun's reply, he raised an eyebrow slightly and his lips curled into a barely perceptible smile.

"She says we must speak to Mother Favianna."

A/N: Starting next month, I'll update every six days. Also I had an idea for a Torchwood/Sherlock crossover that I know I'm never going to get around to writing. I'll leave the summary on my profile if any one wants to write it for me. If you do, lemme know and give me credit for the idea.
