Perhaps the attached would be a good starting point for you.

A certain king had a beautiful garden, and in the garden stood a tree which=
 bore golden apples. These apples were always counted, and about the time w=
hen they began to grow ripe it was found that every night one of them was g=
one. The king became very angry at this, and ordered the gardener to keep w=
atch all night under the tree. The gardener set his eldest son to watch; bu=
t about twelve o'clock he fell asleep, and in the morning another of the ap=
ples was missing. Then the second son was ordered to watch; and at midnight=
 he too fell asleep, and in the morning another apple was gone. Then the th=
ird son offered to keep watch; but the gardener at first would not let him,=
 for fear some harm should come to him: however, at last he consented, and =
the young man laid himself under the tree to watch. As the clock struck twe=
lve he heard a rustling noise in the air, and a bird came flying that was o=
f pure gold; and as it was snapping at one of the apples with its beak, the=
 gardener's son jumped up and shot an arrow at it. But the arrow did the bi=
rd no harm; only it dropped a golden feather from its tail, and then flew a=
way. The golden feather was brought to the king in the morning, and all the=
 council was called together. Everyone agreed that it was worth more than a=
ll the wealth of the kingdom: but the king said, 'One feather is of no use =
to me, I must have the whole bird.'
