"They'd shoot up the
neighbourhood, I imagine, if they knew the truth."
Hour after hour we took turns listening at the detectaphone. We
gathered a choice collection of slang and epithets, but very
little real news. However, it was evident that they had a
wholesome respect for both the Chief and the Boss. It seemed that
the real head of the gang, if it was a gang, had disappeared, as
one of the men had already hinted "up-state."
Garrick had meanwhile brought out the other detectaphone box,
which was longer and larger than the oak box.
"This isn't a regular detactaphone," he explained, "but it may
vary the monotony of listening in and sometime I may find occasion
to use it in another way, too."
In one of the long faces were two square holes, from the edges of
which the inside walls focussed back on two smaller, circular
diaphragms. That made the two openings act somewhat like megaphone
horns to still further magnify the sound which was emitted
directly from this receiver without using any earpieces, and could
be listened to anywhere in the room, if we chose.
