The whole village soon learnt that a large sum of money had been lost. Sam Benton,
the local butcher, had lost his wallet while taking his savings to the post-office. Sam
was sure that the wallet must have been found by one of the villagers, but it was
not returned to him. Three months passed, and then one morning, Sam found
his wallet outside his front door. It had been wrapped up in newspaper and it
contained half the money he had lost, to-gether with a note which said: 'A thief,
yes, 'but only 5o per cent a thief!' Two months later, some more money was sent
to Sam with another note:'Only 25 percent a thief now!' In time, all Sam's
money was paid back in this way. The last note said:' I am 100 per cent honest
now!'
