“Your call came from a pay station in a drug store near the water front.”

Bob obtained the name of the drug store and he whirled away from the desk and ran outside to the taxi stand. He jumped into the first cab and gave the address of the drug store.

“Step on it driver. I’ll clear you with any traffic officer that stops us.”

“I’ve heard that story before,” grunted the driver as he shifted the gears.

“This talks,” said Bob, shoving his badge into view of the driver.

“You said it, mister,” said the taxi man, and the cab leaped ahead as he trod heavily on the accelerator.

The cab wove in and out of a web of traffic, then shot away down a dark street, took several corners on two wheels, and after threading through several narrower streets, drew up beside a well lighted corner drug store.

“Wait here,” ordered Bob, jumping from the cab and hurrying into the store.

Two clerks were on duty and Bob addressed himself to the older man.

Motioning toward the telephone booth at the rear of the store, he fired his first question.
