“And Mrs. Deline brought that package from the lighthouse,” Penny interposed eagerly. “Mr. McCoy must have given it to her.”
“What’s the plan of action?” Mr. Parker demanded. “Army men already have gone to the lighthouse to search that place thoroughly.”
“Our job is to keep watch of the dune where the package was buried. Naturally we have no way of knowing what time anyone will show up there. It may be an all night wait.”
“I’ll be with you in a minute,” Mr. Parker declared. “Just as soon as I get an overcoat.”
He started toward the elevator, then came back to the group.
“What about Mrs. Deline?” he asked. “She’s here in the hotel. Went to her room only a few minutes ago.”
“She’ll be placed under arrest,” Jerry said. “Better call her on the telephone and get her down here. Don’t let her suspect that you think anything is wrong.”
Mr. Parker vanished into the nearest telephone booth.
“I can’t understand it,” Penny murmured to Jerry. “I was sure Dad was head over heels in love with Mrs. Deline. Why, it didn’t even seem to ruffle him when he learned the truth about her.”
Jerry grinned. “Maybe,” he drawled, “that was because he knew all the time.”
