The lighthouse keeper's lunch - Ronda Armitage

Once there was a lighthouse keeper called Mr. Grinling. At night
time he lived in a small white cottage perched high on the cliffs,
and in the daytime he rowed out to his lighthouse to clean and
polish the light.
Every day Mr Grinling tucks into delicious lunch, prepared by his
wife, Mrs Grinling. But Mr Grinling isn't the only one who enjoys
the tasty food, so Mrs Grinling has to think of a way to stop the
greedy seagulls from stealing the lighthouse keeper's lunch.
First published forty years ago, THE LIGHTHOUSE KEEPER'S LUNCH has
become a modern picture book classic and is loved by children everywhere.
