"First you tell me that I disturb your plans; then you want to know if I am preoccupied. You would like to have me as an 'extra' in the subscription."

As they came out on the flags by the gondola, another boat was pushing a black prow into the rio from the Misericordia canal. It came up to the water-steps where the two stood. Caspar Severance stepped out.

"Caspar!" Miss Barton laughed.

"They told me you were here for dinner," he explained. He was in evening clothes, a Roman cloak hanging from his shoulders. He looked, standing on the steps below the other two, like an impertinent intrusion.

"Lawrence! I thought you were on your way home."

Lawrence shook his head. All three were silent, wondering who would dare to open the final theme.

"The Signora Contessa had a headache," Miss Barton began, nonchalantly.

Severance glanced skeptically at the young American by her side.

"So you fetched il dottore americano? Well, Giovanni is waiting to carry us home."

Miss Barton stepped forward slowly, as if to enter the last gondola whose prow was nuzzling by the steps.
