The final exciting instalment in the Miss Penny Dreadful series from acclaimed author Allison Rushby.

Searching for a new story idea for her aunt’s famous penny dreadfuls, Penny and Aunt Harriet decide to follow up a newspaper article about a mysterious mermaid’s grotto. Hidden down a secret passageway on the banks of the River Thames, the only way to enter is through a tavern, aptly named The Mermaid’s Locks.

In the glittering grotto, Penny and her aunt find a comb with some strands of the mermaid’s red-gold hair. Penny sets out to investigate - can the mermaid truly be real? Also, why doesn’t Mr Crowley, Aunt Harriet’s publisher, want her to write about it? Meanwhile, another cryptic postcard arrives from Penny’s missing parents. Nothing is as it seems in Penny’s world. Will Penny be able to finally piece together all the clues?


Allison Rushby, the daughter of an author, was raised on a wholesome and steady diet of classic English literature. Some of her favourite books, re-read countless dog-eared times include Rumer Godden's The Dolls' House, Frances Hodgson Burnett's The Secret Garden, Dodie Smith's I Capture the Castle and Noel Streatfeild's "Shoes" series. She has long been a fan of cities with long, winding histories, wild, overgrown cemeteries, red brick Victorian museums, foxes and ivy. She prefers to write with a cup of Darjeeling tea by her side and a Devon Rex cat curled up in her lap.

Bronte Rose Marando is a Sydney based illustrator. Her whimsical artwork is influenced by our natural world, a love of narrative, the unknown and all things mysterious and magical. When she isn’t drawing you can find Bronte with her nose in a good book or wandering about antique stores.


Our youngest readers deserve such rich and magical book offerings. Though sophisticated, Penny Dreadful is engaging and accessible, with gentle humour, whimsical illustrations, intriguing history and mystery elements.
