Miss Endicott - Part 2

Prudence Endicott is the daughter of London's Conciliator – the voice
and hope of the little people. Will she be able to pick up the torch
after her mother dies? Volume 2 of 2. Miss Endicott's life as a
Conciliator is off to a bad start: a strange plot is being hatched in
the tunnels beneath London, her headquarters have been torched, the
child whose nanny she is by day has disappeared while following her
at night … and to top it all, her mother, whom everyone believed
dead, has reappeared! A blessing, or a curse? Can two Conciliators
together defeat the mysterious master – assuming two Conciliators
could ever work together?
