Bridge mysteries may baffle a detective

A.A. Milne, in The Red House Mystery, wrote, "Like all really nice people, you have a weakness for detective stories, and feel that there are not enough of them. So, after all that you have done for me, the least that I can do for you is to write you one."

Some bridge deals are like mystery stories - what is the winning play or defense? Others just have a baffling aspect. For example, in today's deal, look only at the South hand. After three passes, South opens one club, West overcalls one heart, North passes, and East raises to two hearts. What should South do now?

Once you have decided, look at the North hand. Do you agree with the pass over one heart?
