Siobhan’s first novel, A Swift Pure Cry, was published in 2004 to great critical acclaim and was followed quickly by three more multi-award winning titles; The London Eye Mystery, Bog Child and  Solace of the Road.  Her titles have been nominated for over 65 awards and The London Eye Mystery was adapted for the stage by the Unicorn Theatre in 2009. Before her writing career began she worked for the writers’ organisation PEN and her work both in the UK and US included founding and leading the Rushdie defence committee and travelling widely to investigate human rights conditions for writers.

Solace of the Road, The London Eye Mystery and Bog Child have all been adapted into plays. Solace (adapted by Mike Kenny) most recently had a run at the Derby Theatre.

Siobhan died in 2007 but left behind not only four memorable novels but also the roots of others. One such idea became A Monster Calls (Walker) which Patrick Ness wrote inspired by her opening salvo. Jim Kay illustrated the novel and the 2016 film adaptation starred Liam Neeson and Felicity Jones.

Robin Stevens, author of the Murder Most Unladylike Mysteries, helped continue Siobhan’s legacy with The Guggenheim Mystery, a sequel to The London Eye Mystery, published in 2018 from Puffin Books.
