descride the malay man catcher. what does it do for zaroff?

From the text:

But he was not quite quick enough; the dead tree, delicately adjusted to rest on the cut living one, crashed down and struck the general a glancing blow on the shoulder as it fell; but for his alertness, he must have been smashed beneath it.

The Maylay man-catcher injures the General, but not badly enough to interfere with the game. He plans to return when his wound is dressed.
