When Enola Holmes encounters her friend Lady Cecily hiding behind a peculiar pink fan, she finds it strange and unsettling. Lady Cecily is being held hostage in an abysmal orphanage, coerced into a miserable marriage.

Enola joins forces with her much older, famous brother, Sherlock Holmes, whom she has fought desperately to elude, and risks her own freedom to rescue her friend.

As Enola and Sherlock delve deeper into the mystery, they must navigate the treacherous streets of Victorian London and confront dangerous foes to free Lady Cecily from her dire predicament.

Some believe the arms of the Venus de Milo statue are lost to antiquity.

Perhaps not.

1934. When Daisy Wells and Hazel Wong set up a secret detective agency at Deepdean School for Girls, they struggle to find a truly exciting mystery to investigate. (Unless you count the case of Lavinia's missing tie. Which they don't.)

But then Hazel discovers the body of the Science Mistress, Miss Bell - but when she and Daisy return five minutes later, the body has disappeared. Now the girls have to solve a murder, and prove a murder has happened in the first place before the killer strikes again (and before the police can get there first, naturally).

But will they succeed? And can their friendship stand the test?

Hours after Holmes and Russell return from solving the murky riddle of The Moor, a bloodied but oddly familiar stranger pounds desperately on their front door, pleading for their help. When he recovers, he lays before them the story of the enigmatic Marsh Hughenfort, younger brother of the Duke of Beauville. Marsh has returned to England upon his brother's death, determined to learn the truth about the untimely death of the hall's expected heir—a puzzle he is convinced only Holmes and Russell can solve.

It's a mystery that begins during the Great War of 1918, when young Gabriel Hughenfort, the late Duke's only son, died amidst scandalous rumors that have haunted the family ever since. While Holmes heads to London to uncover the truth of Gabriel's war record, Russell joins an ill-fated shooting party. A missing diary, a purloined bundle of letters, and a trail of ominous clues comprise a mystery that will call for Holmes's cleverest disguises and Russell's most daring journeys into the unknown—from an English hamlet to the city of Paris to the wild prairie of the New World.

The trap is set, the game is afoot, but can they catch an elusive villain in the act of murder before they become his next victims?
