Presently they heard footsteps on the hard floor of the gangway, and then a light such as those being used by the boys flashed out.
"Now we're in for it!" exclaimed Tommy.
"For the love of Mike, don't let him see us!" whispered Jimmie.
"It'll spoil everything if he does," Dick submitted.
The boys crowded close against the wall of the gangway and waited impatiently for Ventner to pass along.
He was muttering to himself as he moved down the gangway, and his round, protruding belly and his little shapeless shoulders reminded the watching lads of the gnomes they had read about, living in underground cells and preying at night upon the fairies.
Only for a trifling accident the boys would certainly have been discovered. Just as the detective came to a position ten or fifteen feet from where they were standing, when he was in a position to see their faces by the rays cast on ahead by the flashlight, he partly turned his ankle in a stumble on the rails, and for a moment the rays of the light were directed downward. He hobbled along, raving and cursing, for a few steps and then walked briskly on again.
But the ever-watchful eye of the searchlight no longer struck upon the wall where the boys stood, and they realized that for the present they were safe from discovery. Ventner moved on down the gangway and soon disappeared in a cross cutting which ran to the right.
"That's lucky!" exclaimed Jimmie.
"Why didn't we geezle him?" demanded Tommy.
