Eight Million Dollars From Mars!

Pauker had killed ten men to get eight million dollars. Now his flight to Mars would insure his safety from justice. Or would it?
His poise was perfect as he crossed the concourse with the highly vaulted ceiling. He moved with purpose but not in haste, his arms swinging freely, eyes straight ahead. At his heels, the squat, robot luggage-carrier dutifully followed the bone which he carried in his right hand.
At the long baggage counter, the husky, human attendant took the bone and led the carrier under the counter through the low passage onto a platform scale. He whistled. That'll be $4,175.00 excess baggage, he said.
Pauker nodded curtly and withdrew his billfold. He laid his ticket and the currency on the counter while the attendant clipped paper tags to the handles of his four bags, broke off the stubs at the perforations, shoved the luggage off the cart onto a moving belt and replaced the bone in its homing slot. The three-wheel robot rolled off the scales, out the short tunnel under the counter and headed back for the entrance.
We don't see many leather bags here, the man said pleasantly. They weigh up too much.
Pauker's eyes darted to the man's face nervously as he examined the ticket and made change. Was there suspicion in the young, bland features?
The traveler was well aware of the extravagance of his heavy bags, and he knew that most interplanetary trippers used the lightest, flimsiest containers to remain under the 100-pound limit. At the risk of appearing conspicuous, Pauker had decided on the stronger suit-cases. There must be no chance of an accidental rupture of his luggage. Legitimate people don't haul bundles of $1,000 interplanetary bills around with them—not eight million dollars worth.
But it wasn't the young man's remark that broke his composure. It was the sight of his four bags bouncing along the endless belt and disappearing through an arch into the next room. Suppose customs got nosey?
Normally, his research had revealed, only a cursory X-ray for weapons was made, and he had delayed checking them through until the last moment, so it was unlikely they would hold them up. Yet the fear clutched his belly. He snatched at the baggage tags, his ticket and change, jammed them in his valuables pouch which was fastened to his belt, and moved hastily out of the depot.
