As months passed, Blake watched the far-off, forbidding structure with an oddly mounting interest. Since the vast windows were never lighted, he knew that it must be vacant. The longer he watched, the more his imagination worked, till at length he began to fancy curious things. He believed that a vague, singular aura of desolation hovered over the place, so that even the pigeons and swallows shunned its smoky eaves. Around other towers and belfries his glass would reveal great flocks of birds, but here they never rested. At least, that is what he thought and set down in his diary. He pointed the place out to several friends, but none of them had even been on Federal Hill or possessed the faintest notion of what the church was or had been.
