Waiting patiently, Shayne sucked on his cigarette, expelling great clouds of smoke through flaring nostrils. The coupé did not move away from the curb.

There was little traffic on Second Avenue. A lopsided moon and millions of brilliant stars shed silvery light upon the Magic City. A faint cooling breeze blew in from Biscayne Bay, salt-tanged and permeated with the perfume of flowers from Bayfront Park, bringing relief from the long sun-drenched August day.

Shayne threw his cigarette away and started his motor. He swung about in a U turn and drove slowly to Southeast Second Street. He smiled grimly when the coupé twisted away from the curb and made a U turn behind him.

He stopped wasting time watching the little car and angled over to Biscayne Boulevard. He drove north at a moderate speed, dragging in deep breaths of the cool, tangy air.

The coupé was a block behind him when he approached the traffic light at Seventy-Ninth Street. A line of traffic was piling up behind the little car trailing him.

Shayne gauged his speed carefully, reached the corner as the traffic signal changed from red to green, then pulled into a filling-station on the southeast corner of the busy intersection.

The driver of the coupé hesitated, slowed behind him. A furious medley of honking broke out as the drivers behind the coupé saw themselves about to be held up while the light changed.

Reluctantly, the coupé drove into the intersection, hesitated about turning right or left, drove on across and pulled to the curb half a block ahead.

A courteous attendant was standing smartly at attention beside the detective’s car. Shayne grinned at him and said, “Sorry, bud, I just remembered an important appointment. Guess I’ve got enough gas to make it. Back later.”

He slammed in the gears and drove on through the station into Seventy-Ninth Street, joining a stream of traffic flying across the northern causeway to the peninsula. He smiled happily when he saw, through the rearview mirror, that the coupé was taking a desperate chance to make a U turn on the boulevard and speeding back to the intersection to follow him.
