"Isn't it pretty? Aren't you glad we brought you?" Bonnie demanded as they pushed through the crowd.
The lecturer did not answer, for she caught sight of the Latin professor hurrying toward them.
"Miss Henderson! I was afraid you were lost. It is nearly half-past eight. The audience has been waiting, and we have been filling in the time with reports."
For a moment the lecturer was silent, being occupied with an amused scrutiny of the faces of her captors; and then she rose to the occasion like a lady and a scholar, and delivered a masterly apology, with never a reference to her sojourn on the fence.
Bonnie and Priscilla stared at each other without a word, and as Miss Henderson was led away to the remnants of her audience Patty suddenly appeared.
"Good evening, Mr. Sherlock Holmes and Dr. Watson. Did you solve your mystery?" she asked sweetly.
Priscilla turned her to the light and scrutinized her face.
Patty smiled back with wide-open, innocent eyes.
Priscilla knew the expression, and she shook her. "You little wretch!" she exclaimed.
Patty squirmed out from under her grasp. "If you remember," she murmured, "I once said that the Lick Observatory was in Dublin, Ireland. It was a very funny mistake, of course, but I know of others that are funnier."
