Mr. Chan and Mr. Lee agreed in May 2002 that Mr. Chan would sell 100 copies of "Success in Law" to Mr. Lee in August 2002 and that upon receipt of the books Mr. Lee would pay Mr. Chan $10,000. In June 2002 Mr. Chan said to Mr. Lee that he would not deliver the books in August 2002 without explanation and insists that Mr. Lee can get the copies from another booksellers.

Advise Mr. Lee what he can do.
