     Some people believe that a Robin Hood is at work, others that a wealthy person simply wants to

distribute his or her fortune before dying. But the donator who started sending envelopes with cash to

deserving causes,accompanied by an article from the local paper, has made a northern German city

believe in fairytales (童话).

     The first envelope was sent to a victim support group. It contained €10,000 with a cutting from the

Braunschiveiger Zeitung about how the group supported a woman who was robbed of her handbag;

similar plain white anonymous (匿名)envelopes, each containing  €10,000, then arrived at a kindergarten

and a church.

     The envelopes keep coming, and; so far at least  €190,000 has been distributed. Last month, one of

them was sent to the newspaper 's own office. It came after a story it published about Tom, a

14-year-old boy who was severely disabled in a swimming accident. The receptionist at the

Braunschiveiger Zeitung opened an anonymous white envelope to find 20 notes of  € 500 inside with

a copy of the article. The name of the family was underlined.

     "I was driving when I heard the news," Claudia Neumann, the boy's mother, told Der Spiegel

magazine. "I had to park on the side of the road; I was speechless."

     The money will be used to make the entrance to their house wheelchair-accessible and for a course

of treatment that their insurance company refused to pay for.

     "For someone to act so selflessly, for this to happen in such a society in which everyone thinks of

himself, was astonishing," Mrs. Neumann said. Her family wonder whether the donator is a Robin Hood

character, taking from banks to give to the needy.

     Henning Noske,the editor of the Braunschiveiger Zeitung, said: "Maybe it is an old person who is

about to die. We just do not know." However, he has told his reporters not to look for the city's hero,

for fear that discovery may stop the donations.
