"Miss Hodge? You wanted to see me?"

"Oh, in my office, Miss O'Donnell."

"You weren't there, so I-"

"Not that it matters, now that you are here. Tell me: when you put up the boom with Miss Rouse last night-It was you who helped her?"

"Yes, Miss Hodge."

"When you put up the boom with her, which end did you take?"

There was a tense moment of silence. It was obvious that O'Donnell did not know which end of the boom had given way and that what she said in the next few seconds would either damn her or save her. But when she spoke it was with a sort of despairing resolution that stamped what she said with truth.

"The wall end, Miss Hodge."

"You put the pin into the upright that is fixed to the wall?"

"Yes."
