The automobile backed slowly across the street through the crazy reversed traffic.

The Shadow’s eyes could not be seen, but the hand was evidence that they were alert. It was writing data, with rapidity.

Halcyon Eight — special sedan — 1930 model — winged radiator cap — side spare tires — mirrors on them — damaged right fender — double-barred bumper -

The data was amazing. Even after the automobile had rolled back out of the picture, The Shadow’s hand was yet at work, putting down every item that might be used to identify the car.

An ordinary observer might have believed that it would be impossible to distinguish one car from another of the same model. The Shadow’s notations belied that fact.

Even though the list included only items that were discernible from a distance, they gave the automobile such a tabulation of individuality that the search could surely have been narrowed down to a comparatively small list of cars.

The Halcyon Eight was an expensive car. It catered to those who desired individuality in automobiles.

The room was in darkness. A low laugh sounded as hollow, echoing merriment. It was a laugh that indicated success.

To The Shadow, the task that lay ahead was not a great one. He had the facts he needed — how the man who had met Marschik had arrived on the scene.

Through the medium of the motion-picture reel, The Shadow had accomplished the impossible. He had made time move backward!
