In Trouble for Lucia, Lucia learns to ride a bicycle and we live through the saga of Blue Birdie (Mrs. Wyse's dead budgerigar [parakeet] invoked in a seance). Lucia and Georgie renew their acquaintance with the operatic diva Olga Braceley and the composer Cortese, but nobody in Tilling believes her when she claims to have entertained a duchess overnight. Lucia becomes Mayor of Tilling and Miss Mapp is appointed her Mayoress. This is the sixth volume in the "Lucia" series.
