But Ted, unfortunately for the success of their plan, stumbled and fell, making so much noise that Mrs.Mooney heard it.
"Thieves! Burglars! Police!" she screamed.
"Come on!" cried Bob desperately.

"We'll be caught!" Mrs.Mooney ran back into the house, slammed the front door, shut and locked it.

She believed she had surprised thieves at work, for she saw two dim forms running toward the street.
"Leg it!" whispered Bob.
"I am," replied Ted.
They reached the gate together, but that was as far as they got, for just as they arrived at it they collided with a large man who was running toward the house.

He was so large that the combined impact of Bob and Ted against him never staggered him, but it almost threw them off their feet.

They were running, head down, and had not seen him.
"Hold hard there, my hearties!" exclaimed the man in a gruff but not unpleasant voice.
