"I see you are determined to follow Christopher Nichols' advice."
"Yes, don't you think I should?"
"I believe he is not considered a very reliable detective," the man replied. "However, in this instance, his advice might be worth following."
"I'm glad you think so, Mr. Cron. I'll take the necklace to the bank in the morning."
"Why not come to my studio before going to the bank?" the art critic proposed. "Then I could serve as an escort. With such a valuable package in your possession you really need a guard."
"It is very kind of you to offer," Mrs. Dillon returned, flattered. "I will meet you at the studio at one o'clock and after luncheon we'll go to the bank together."
Penny had reached the foot of the stairs. The two were so engrossed in their conversation that they were unaware they were blocking the path.
"I beg your pardon," she murmured suggestively.
"Oh, I'm so sorry!" Mrs. Dillon exclaimed, moving hastily aside.
Penny gave no hint either by look or action that she had overheard the conversation, but inwardly she raged at Hanley Cron's cutting reference to her father's ability. She slowly climbed the stairs. At the first landing she glanced back over her shoulder and noticed that the art critic was staring after her. His expression startled her.
