But Carlson did not leave alone. Kip Burland, without asking permission from anybody or even saying good-night to Barbara, slipped quietly from the house. He was particularly interested in the urgent business which was pressing Mr. Jack Carlson.
CHAPTER VII
The Trail Of The Beam
If Jack Carlson was as innocent as he pretended to be, it was curious that he should stop just outside the gate of the Weedham home, reach into a bed of dwarf evergreens from which he took a long copper cylinder which closely resembled a flashlight.
From his hiding place in the shadows, Kip Burland saw this move on the part of Carlson. He then saw Carlson get into his car and drive away. Burland hailed a passing cab, ordered the driver to keep Carlson's car in sight.
Carlson drove down into the lower east side of town, parked his car in a narrow street, and got out. Kip ordered his cab to pass Carlson's car. Looking back through the rear window, he saw Carlson turn up a narrow walk between two tenement buildings.
"Stop here," Kip ordered the cab driver. And as the taxi braked, he got out, threw a bill to the driver, and ran up the street toward the place where Carlson had disappeared.
In the dusky shadows between the two tenements, Burland watched Carlson put something into a wooden milk box attached just outside what was apparently someone's kitchen door. Then Kip had to duck back into a darkened doorway as Carlson retraced his steps, and got back into his car.
Kip had to make a choice quickly. Either he continued to follow Carlson or he investigated the milk box which Carlson had mysteriously visited. In as much as there was no taxi in sight, Kip decided on the latter course. As soon as Carlson was out of sight, he left the doorway, went up the walk between the two buildings, opened the milk box.
