"His father recently passed away", he added. "The native followed the map and led me to this site on the condition that if we discovered anything of value he would be paid one thousand dollars", explained Bob. "And what is it that you found buried,?" asked Detective Thompson.

"It's just terrific," exclaimed Bob, "we found 3 gold coins of various sizes dated 400 B.C., and after properly dusting them off I found them to be in excellent condition." "I quickly paid the native to complete our verbal contract and keep him from trying to claim a portion of the discovery," concluded Bob.
