Explanation:

In the context of this poem, the walls do no seem to be a structure designed to keep a foe out, but rather to trap something within. The telltale sign that the walls are perhaps not a beneficial thing is the word narrow.

Walls can be protective, but in a narrow context it is implied that the barrier causes suffocation and perhaps claustrofobia.

from the excerpt from the "the dark game" the reader can infer that folke cronholm was spying for the allied nations.
