Alleluia is surprised to see her again, but understands when asked the question, and provides what Jovah can tell her about Micaiah's birthplace.
It's not too far. It's in Semorrah. (Why does he keep reminding her of the angelica Rachel?)
She flies to Semorrah, and finds the records hall, and inquires after Canaan and Judith.
And she is sure to act sufficiently aloof that no one asks why.
She finds this address, and she sits on the roof of the stack of apartments across the street from it to see what she can see.
Introducing herself would let Micaiah's parents find her - and hence Micaiah. If she can determine that Nathaniel is no longer at this house, or that he's happy, she can just go.
If she determines that Nathaniel is present and unhappy, things are more complicated, but she can tell her father not to let anyone of Canaan's description into the Eyrie.
Isabella decides to wait. She will interrupt if anything dreadful happens, but it will be easier if she can catch Nathaniel while he's out of the house away from his parents.
Isabella glides down from the roof, concocting a half-baked story, and knocks on the door.
"Hello! The Eyrie children's choir director is hoping to add some voices from a little farther afield than the Eyrie itself and Velora at the Gloria this year." (This is actually true.) "I'm helping him look." (This is true in the sense that if she picks up Nathaniel and carries him away she may as well try slotting him into the children's choir.) "I noticed a little boy the right age through the window. Is there any chance I can meet him?"
Isabella repeats the out-of-context fact about the director wanting voices from farther afield and having seen Nathaniel through the window.
"Is there someplace I can talk to your son where some singing won't bother anyone?" Isabella asks with a winning smile.
She doesn't like it, but her cover story doesn't have an opening for pushiness.
"Of course. I'll be back then. Do you happen to know if there are any restaurants here with angel chairs?" Isabella asks.
Isabella thanks her. She goes there. She eats lunch, and minds the time, and, an hour later, returns to the house.
