Author Description

Twenty-third in the long-running mystery series with Dr Launcelot Priestley. Victor Harleston awoke with uncharacteristic optimism. Today he would be rich at last. Half an hour later, he gulped down his breakfast coffee and pitched to the floor, gasping and twitching. A local doctor was summoned and almost instantly on his arrival recognised that it was a fatal poisoning - and a case for Scotland Yard. 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.
