Murder Must Advertise

Author’s Note

I do not suppose that there is a more harmless and law-abiding set of people in the world than the Advertising Experts of Great Britain. The idea that any crime could possibly be perpetrated on advertising premises is one that could only occur to the ill-regulated fancy of a detective novelist, trained to fasten the guilt upon the Most Unlikely Person. If, in the course of this fantasy, I have unintentionally used a name or slogan suggestive of any existing person, firm or commodity, it is by sheer accident, and is not intended to cast the slightest reflection upon any actual commodity, firm or person.
