They took me slumming, where gaunt walls of brick
Bulge outward with a viscous stored-up evil,
And twisted faces, thronging foul and thick,
Wink messages to alien god and devil.
A million fires were blazing in the streets,
And from flat roofs a furtive few would fly
Bedraggled birds into the yawning sky
While hidden drums droned on with measured beats.
I knew those fires were brewing monstrous things,
And that those birds of space had been Outside –
I guessed to what dark planet's crypts they plied,
And what they brought from Thog beneath their wings.
The others laughed – till struck too mute to speak
By what they glimpsed in one bird's evil beak.
