The drugstore on Sixth Avenue looked like any other drugstore on Sixth Avenue. Or any other avenue. That is, it looked that way from the front. There were counters behind which were all the thousand and one items carried by modern drugstores. There was a prescription counter along one side. A gleaming soda fountain ranged along the other side. At the soda fountain sat a customer, a Negro, gangling, lean, looking sleepy and stupid. But this was Josh Newton, graduate with high honors from Tuskegee and an aide of Richard Henry Benson, known to the underworld as The Avenger. And the store, with its normal, ordinary look, was just as deceptive as Josh Newton. For it wasn’t ordinary at all. You could have found that out by going into the rear room. The rear room was twice as big as the front. And it had no store supplies. It was a dual laboratory, with chemical apparatus on one side and electrical on the other.
