At this point in the story, Mrs. Basil E. Frankweiler’s role becomes clearer: she’s a wealthy art collector and Angel’s previous owner. Angel’s significance also comes into focus. If Michelangelo really
did carve Angel, then presumably it would be worth a
lot more money. Yet the statue sold very cheaply, which raises questions about its origins and authenticity. The inclusion of these details suggests that the mystery surrounding Angel will be significant as the book progresses. Mrs. Frankweiler also mentions her collection of filing cabinets, another detail that will be significant later.
