Edgar Wallace (1875–1932) has 2 books in the BigBookHub catalogue: The Black Abbot and The valley of ghosts.

Wallace spins a mystery where a shadowy criminal society and a seemingly incidental death spiral into a labyrinth of false leads and moral ambiguity, delivered in brisk prose that influenced decades of thriller writers. The puzzle matters less than the atmosphere of corruption and hidden power.

A crime novel by Edgar Wallace, first serialised in The Popular Magazine in four installments in 1922. It was issued in book form in the UK by Odhams Ltd. in London that year and in the US in 1923.
