“What’s become of him?” asked Jack.

“I guess he’s skipped out,” answered Sid.  “After holding up Ida it won’t be safe for him to linger too close to these parts.”

“I should say not,” commented Cora.

“Now, will you take this money, and—­and call it square?” asked Sid nervously.

“Hardly square,” murmured Jack.  “Look at the suspicions about my sister—­”

“Hush, Jack,” pleaded Cora, looking at Ida, who was weeping.

“I think the best way will be to call the incident a closed one,” decided Ed.  “I’ll take the money, and—­”

“What will you tell the police?” asked Jack.

“I’ll tell them the money came back to me in a mysterious way.”

“They may want to claim the reward.”

“They can’t.  There is only one person who will get the reward, and she is—­”

He paused and walked over until he stood in front of Ida, who sat with bowed head.

“Miss Giles, it is due to you, more than to any, one, that this mystery is solved,” he said:  “Will you please accept the reward?” and he took some bills off the roll Sid had handed him.

“I couldn’t oh, I couldn’t!” she sobbed.

Ed looked embarrassed.  Every one was under a strain.  Jack went to the safe and took out the diamond ring.

“I guess that comes back to you,” he said to Sid, “as long as you’ve made up to Ed the whole sum.”

Sid took it hesitatingly.  Then with a quick motion he stepped up to Ed.

“Here,” he exclaimed, “this belongs to you.”

“What for?”

“Interest on your money.  It’s more than the ring cost, maybe, considering the loss on the bank stock, but I’ll make it up later.”

“No,” said Ed after a moment’s thought “We’ll call it settled.”

He held the ring in his hand and went over to the weeping girl.

“Will you—­will you accept this for what you have done for me—­for all of us?” he asked gently.

Ida looked up through—­her tears.  Then she shook her head.

“Let me give it to her,” whispered Cora, and Ed handed over the sparkling gem.

“Take it from me, Ida,” whispered Jack’s sister.  “Let it be a pledge of—­of whatever you like.”

“A pledge from an up-to-date motor girl!” cried Jack gaily, and his words ended the strain that was on them all.

Sid slipped out, and Ida was led away by Cora.  Then such talking as there was between Ed and Jack!

“Well, did you ever hear such a yarn?” asked Jack.  “Did you suspect him, Ed?”

“Yes, but I thought his motive was a different one.  I had an idea the strain would soon tell on him—­or Ida.  I’m glad it’s over.”

“So am I!” exclaimed Cora, coming into the room, having parted from Ida.  “Oh, I feel years younger!”

“Look out!” warned Ed.  “You’ll soon be a mere infant again if you keep on.”

“I don’t care!” she cried.  “Come on out and take a long run in the Whirlwind.  I want to get some of the cobwebs swept off my brain with a glorious breeze.  Come, Jack—­Ed.”
