Maybe, THE WICKED PIGEON LADIES IN THE GARDEN By Mary Chase.
back my bracelet,"" intones eldest Messerman sister, sometimes pigeon,
Ingrid, and you know that the leprechaun in the tangled garden isn't
pretending: Maureen Swanson had better watch out. You know too that
you've got ahold of a ghost story, and happily this one doesn't dissolve
into a dream--although rebellious Maureen does find herself back in the
sisters' childhood; and it doesn't turn into a lesson--although she does
assume responsibility for their fate, the first responsibility she's
ever accepted. But mostly this is Maureen, the scourge of the
neighborhood, vs. the pigeon ladies who are ""fancy dressers, high
flyers, smooth talkers and hard haters,"" and if Maureen's a little slow
to catch on for a while, the danger of vanishing forever triggers a
fight to the let's-UNpretend finish. The pigeon ladies leave to do their
worst elsewhere, Maureen is a little better, closing but not strangling
a quick-witted, sharp-tongued entertainment."
