“Thinking about banshees, Margo?”

“Why, yes.” Momentarily surprised, Margo laughed it off. “I suppose a lot of other people are, too.”

“Miss Sylvia Selmore for one,” informed Cranston. “I forgot to tell you that she postponed her trip to Florida today.”

Still staring at the darkness, Margo asked why.

“Sylvia wants to attend more seances,” explained Cranston. “She hopes for another manifestation of the Gwrach y Rhibyn.”

Remembering the tense scene in the seance parlor, Margo wasn’t inclined to laugh.

“Of course the Canhywllah Cryth must appear first,” assured Cranston. “We saw it again in the park last night. Remember?”

Margo did remember. She shuddered; then asked in hollow tone:

“That creature near the transverse. Did it - did it really materialize when those lights appeared - over there?”

Staring straight across the park, Margo was looking toward the dimly outlined tower of a building, the same one she had noted the night before.
