# Through the Roof explained — The Secret of the Old Mill

> Chapter companion for The Secret of the Old Mill by Franklin W. Dixon.

## What happens

Frank and Joe Hardy, having narrowly avoided detection by Markel, climb a willow tree to reach the mill's roof. They enlarge a hole in the weakened roof and descend into an attic, then through a trapdoor into an empty room below. From there, they confirm that the counterfeiters' workroom is directly beneath them, hearing the machinery and voices.

## Key lines

> The Hardy boys always said that the few seconds in which they stood in the shadow of the willow tree with the suspicious Markel almost within arm's length of them, not knowing whether they had been discovered or not, were the longest seconds they had ever known.

The Hardy boys later recalled that the moment they hid under the willow tree, with Markel nearby and uncertain if they were seen, felt like an eternity.

_Highlights the tension and close call with Markel._

> We've struck them at the right time. They must do their work at night.

Joe realizes they have arrived while the counterfeiters are active, suggesting the operation runs at night.

_Confirms the timing of the counterfeiting activity._

> The mill roof was not on an abrupt slant, so that the boys were able to make their way along among the shingles without a great deal of difficulty.

The roof's gentle slope allowed the boys to move across it relatively easily.
