Murder in Four Degrees

When the famous editor of Lord Cheverdale's paper, the Daily Sentinel, is found brutally killed on the grounds of his Lordship's residence in Regents Park, his money and jewellery are still on him, but his pockets, usually bulging with papers, are empty.

According to Scotland Yard, it must be a political murder. But the experienced ex-C.I.D. Chaney and his able assistant, young Camberwell, suspect that the solution may not be as simple as it seems. The two detectives engage in a careful investigation, following suspects close to the victim in a search that leads them over France and England and that costs more lives before they finally corner the perpetrator of such cold-blooded crimes.
