The Kitty Peck Mysteries

Kitty Peck is taking on the underworld of London's East End.
The Music Hall Murders:

It's 1880 and dancing girls are going missing from 'Paradise' - the criminal manor run with ruthless efficiency by the ferocious Lady Ginger.

Bold, impetuous and blessed with more brains than she cares to admit, Kitty, with the help of her stagehand friend, Lucca, is left to unravel the truth and ensure that more girls do not meet with a similar fate.
The Child of Ill-Fortune:

A year later, and Kitty Peck is the reluctant heiress to 'Paradise'. Far from the colour and camaraderie of the music hall where Kitty had been working, this new position brings with it isolation and uncertainty. Desperate to reconnect with Joey, her estranged brother, Kitty travels to Paris, but the joy of the reunion is overshadowed by his request for her to take a child back to London. Within days of her return it's clear that someone has followed them - and that this someone is determined to kill the child, along with anyone who stands in their way...
