“Yes; whoever it was knew the layout of the house, the habits of its inmates, and where valuables were kept.”

“Why, Jack!” cried Patricia, her eyes dilating with a dawning suspicion. “Who—”

“Better not put anything into words, Pat,” Jack said quickly; “probably we’re all wrong. I hope so. Let’s try to forget all about it. The authorities will take care of it; it’s their business, not ours.”

In spite of Jack’s good advice, Patricia could not keep from dwelling on the subject rather constantly for the rest of the week, especially since the robbery was the Gang’s principal theme of conversation.

“Mrs. Brock,” announced Katharine on Thursday night, “is offering a large reward for the return of her grandfather’s watch alone. It’s a valuable heirloom, and she cares more for that than for the rest of the jewelry. Don’t I wish I could go out some morning, pick up the timepiece, and take it over to her!”

“I guess none of us would object to some extra money,” laughed Anne. “If you weren’t going home this week end, Pat, we might organize a searching party and beat Kath out.”

“Go ahead, anyway,” advised Patricia, pulling out her bag and beginning to pack it ready for an early start the next afternoon. “You’d better get your things together, Jane; we won’t have any time after lunch tomorrow.”

“Jane going with you?” inquired Anne somewhat wistfully.

“Yes. Want to come, too?”

Do I! You’re a peach.” Anne hugged Patricia, and departed for her own room, stumbling over the doorstop as she went out.
