"One murder was bad enough -- The unpleasant publicity could ruin the Cassand's preparations for their fabulous garden party. But the guest shrugged it off and came anyway.

"The third murder couldn't be ignored -- the corpse was indelicate enough to show up right at the party."
An Albert Campion mystery -- pretty much as good as Lord Peter Wimsey!
