The servant entered the room, and said to King Charles worriedly.

-Sorry to bother you, but there is something important my lord.

King Charles was at the breakfast table.  There were boiled egg, fruit salad, cake,  biscuits and tea on the table. He asked 

-“What is the problem?”

-“Ravens, your excellency. One raven is missing in the London Tower.”

- King Charles  said  “Call the police immediately!” He got dressed quickly, got in his car and  went to the London Tower. 

Ravens are very important for them. Because kingdom may fall  if there are less than six ravens in the London Tower. Everybody was so anxious. Police thought that it might be a theft. They asked many questions, searched the city all, but they couldn’t find the raven. King Charles got very angry and said, 

-“Call  Sherlock Holmes!”

Sherlock Holmes was a very smart and successful detective. He came to the tower quickly and examined the everywhere very carefully.

The tower and its environment were  so safe. Beefeaters - guards of London Tower- were very careful. Nobody  could  harm the ravens. 

He spoke the ravenmaster.

-How long are you keeper of the ravens?

-Just for two weeks, sir.

-What is the matter with the previous  ravenmaster?

-He is ill. He has a broken leg.

-What is the name of missing raven?

-Merlina.

-Take me to their cage. 

I want to see them and their cage.

Holmes examined the cage and  other ravens. They were eating a lot, but not flying much. They were fat. He saw some drops of blood and feathers by the door of  the cage.

He figured out that 

Merlina was injured. 

Because of the

inexperienced ravenmaster,  it gained  a lot of weight.  While it was  getting out of the cage's door in difficulties, he hurted its wing. He thought that  it couldn't  fly  away. He looked around the cage again and he found  the  raven between the garden wall and the cage.  A veterinarian examined and treated it.

 Because Merlina never left the tower, there was no danger for the kingdom since the beginning of the problem. King Charles is very happy with his ravens now.
