Well, at least finding her was easy enough. 

She drags the waterlogged body back to the surface, turns back, re-dresses, and picks at the scab on her lip enough to get the blood to mark the sigil. 

Before she has to, the Fading Music-Hall Singer chokes and expels the river water from her lungs. She sucks in a heaving breath, then coughs several times. Then her head falls back to the ground, and she starts... singing. Is that a song? Her neck convulses as if the muscles of her throat are in revolt. But the effect is weirdly calming. Each note follows the last like a stylishly dressed assassin: dramatic, unexpected, inevitable.

...Huh. 

She sits back and listens. 

The song is fairly short. After it's done, the Singer's eyes open.

"I couldn't leave her," she rasps. "But I couldn't get her out."

"Who's 'her'?"

"Clarabelle. My sister... in that madhouse. The Hotel. That's how they found me."

"They caught you trying to jailbreak her?"

"No, they just knew-" She coughs again. "I wouldn't be far."

"Okay. This is very important--what do you know about an entity that may or may not be a diamond the size of a cow?"

"That- that damned jewel," she says sleepily. "I never - never saw it - but... Poor..."

She lapses into unconsciousness.

Hoo boy. Fine. 

She picks up the unconscious Singer and starts carrying her towards the Sensible Under-Secretary's house as discreetly as possible. 

It's surprising how discreetly one can carry a severely bludgeoned woman through a crowded city if one sets their mind to it. She reaches the Sensible Under-Secretary's house unimpeded.

He opens the door and gasps aloud when he sees his former lover. "I- what happened?"

"She got attacked, I rescued her, I tried to ask her about some stuff, she fainted, I figured I'd bring her here so she could find out the baby was alive sooner rather than later."

He bites his lip, but nods. "I'll, I'll put her in the guest bed, I suppose, and send for a physician. Do you know who attacked her?"

She's about to say "someone working for the Masters," but then she remembers that he works for one of the Masters, and while probably he wasn't involved with the attack she doesn't super want to make him feel like he has to choose between keeping something from his boss or not betraying the mother of his child. "She didn't say, before she fainted," she says instead, which is true; the conjecture she has about the attackers' identity came from the person who pointed her towards the stable.

"All right," he says. "I suppose she might say more when she wakes up." He takes his shoulder under the Fading Music-Hall Singer's arm and walks her to his guest bedroom.

She helps him bring her and then sits at the woman's bedside until she wakes. 

She slips in and out of consciousness a few times, but she's too delirious to recognize that there's someone there.

Half an hour passes before the Sensible Under-Secretary comes back with a Somnolent Physician. The Physician examines the Fading Music-Hall Singer.

"This was very nearly a successful assassination," he says grimly. "Her first death was recoverable; had she awoken in the river, however, she'd have drowned and drowned until she faded away. As it is, she's just dealing with several broken bones, a concussion, and blood loss - not so terrible, down here. When she wakes - she probably will fairly soon - give her as much of a bottle of F.F. Gerbrandt's Tincture of Vigour as she'll drink." He places such a bottle on the bedside table. "She'll still be convalescent for a while, but it'll put her in a condition to heal. Might be a few weeks."

The Under-Secretary counts out a fee in jade and sends the Physician on his way.

Lucy waits with bottle and spoon for the next time the Singer slips back to consciousness. 

She wakes up an hour later, lucid enough to be given some Tincture. She drinks it greedily, stopping only after about half the bottle.

Then she looks around, to the extent she can. "Where are we?" she asks.

"Uh, it's sort of a long story. You see, I was conceived on the Elder Continent under mysterious circumstances, and I have strange abilities as a result. So, I started looking for you in the first place because I heard from someone that they'd heard from you about a diamond the size of a cow, and I was concerned that it might actually be a living being who needed help. But you had already disappeared. So I looked through your apartment and found the Sensible Under-Secretary's business card, and I followed him to the graveyard, and uh I brought your baby back to life and left them with him while I went to find you. So we're at his house, because that's where the baby is."

The Singer stares.

"I-" She stops.

"Can I see her," she finally manages.

"Yes," she says, and gets up and runs out of the room to fetch the baby. 

The baby is with the Under-Secretary, who is feeding her from a bottle. He looks up, almost panicked. "Is she-" he begins, and doesn't seem to know how to finish the sentence.

"She's awake and wants to see her daughter."
