Doppelganger - James A. Lindon

Entering the lonely house with my wife
I saw him for the first time
Peering furtively from behind a bush --
Blackness that moved,
A shape amid the shadows,
A momentary glimpse of gleaming eyes
Revealed in the ragged moon.
A closer look (he seemed to turn) might have
Put him to flight forever --
I dared not
(For reasons that I failed to understand),
Though I knew I should act at once.

I puzzled over it, hiding alone,
Watching the woman as she neared the gate.
He came, and I saw him crouching
Night after night.
Night after night
He came, and I saw him crouching,
Watching the woman as she neared the gate.

I puzzled over it, hiding alone --
Though I knew I should act at once,
For reasons that I failed to understand
I dared not
Put him to flight forever.

A closer look (he seemed to turn) might have
Revealed in the ragged moon.
A momentary glimpse of gleaming eyes
A shape amid the shadows,
Blackness that moved.

Peering furtively from behind a bush,
I saw him for the first time,
Entering the lonely house with my wife.
