Headscratchers / Lord Peter Wimsey

• In Murder Must Advertise, why do the cocaine distributors even need advance notice of which pub the system says to distribute at? Can't they just figure it out when they buy the paper, the way their customers do?
  • 'Cause getting it there is more of a production than getting it out in much smaller batches. But why didn't they choose an ad that ran twice: they checked it on Monday and the distributors checked it on Tuesday?
