Wealthy industrialist P. L. Storrs has never approved of lady detectives, and he normally would not have made an exception of Theodolina "Dol" Bonner. But faced with a very delicate problem and surprisingly impressed, he hires her instantly. It seems that Storrs bird-witted wife has fallen under the spell of a smooth-talking religious charlatan, and now Storrs wants Dol to get the goods on him. But when the gorgeous gumshoe arrives at Storrs picturesque country estate, Birchhaven, to meet the scoundrel, she finds more than she bargained for - namely, the corpse of her client and a garden party teeming with suspects! This witty whodunit was first published in 1937.
