"Peterman," I shouted over the roar of the engine, "I think we lost a couple of packages on the last turn."
With a squeal of brakes and grinding of gears, Peterman reversed back up the Casbah's alley. I leaned over the side and pulled the envelope out of the dust just as the jeep lurched forward. The package spun out of my hands and under the rear wheels.
"Sorry," muttered Peterman as he carefully pulled forward a foot so I could retrieve my order. "I was distracted by the blonde in the red silk veil."
Ah, that explained how the tire marks were on both sides of the envelope.
Fortunately, the shirt inside the package was the expected perfection.
