Booklist Review

While investigating suspicious late-night noises in the boardinghouse, Maisie gets knocked out, so she doesn't see the thief, who takes a valuable mask Professor Tobin is preparing to donate to a museum. Once awake again, she collects evidence and follows clues that lead her straight to the thief a young Amazonian boy whose family needs the mask back. As always, the Maisie mysteries provide an enjoyable Victorian romp through the logic of deductive reasoning; this fourth series installment excels by also introducing issues surrounding cultural sensitivity and repatriation of artifacts to the community of origin.--Weisman, Kay Copyright 2016 Booklist
