Death at Breakfast

"At eight o'clock in the morning breakfast was set in the dining room of 8 Matfield Street, the home of Victor Harleston and his sister Janet. But no sooner had Victor Harleston sipped his coffee than his agonised expression and spasmodic twitching conveyed all too clearly that he had been poisoned. When Dr Oldland arrived, he saw that the case was hopeless and called the Yard. Even though, at this early stage, the death of Victor Harleston was surrounded by suspicious circumstances, it was impossible to guess at the extreme ingenuity with which the criminal had carried out his dastardly plan. Despite an almost complete absence of clues, the circumstances were so suspicious that Inspector Hanslet soon referred the evidence to his friend and mentor, Dr Lancelot Priestley, whose deductions revealed a diabolically ingenious murder that would require equally fiendish ingenuity to solve."--Cover.
