Sapper 
Knock Out [EPUB ebook] 

Ronald Standish – the charming, occasional detective who accepts cases when they take his fancy – receives a frantic phone call from a friend, who works for the Secret Service, asking for help. But when the line suddenly goes dead, Standish rushes round to his friend’s Hampstead abode, and is horrified to find him dead, with the receiver still in his hand and a horrific wound to his eye. When Standish teams up with Bulldog Drummond, the tangled political web surrounding this murder and the fearsome risks in pursuing the perpetrators are met head on.
