Darrell Pitt - The Firebird Mystery (Jack Mason Adventure #1)

Welcome to London. A city of fog and snow, filled with airships, steamcars and metrotowers soaring into space.
Before his parents died Jack Mason was an acrobat, travelling around England in the circus. But when the world-famous detective Ignatius Doyle comes looking for a young assistant, Jack's new training begins. And when Scarlet Bell's father disappears, they are all plunged into a mystery so baffling that the future of the whole world may be at stake.
The Firebird Mystery, inspired by the great works of Victorian literature, is an action-adventure for readers of all ages.
