"Oh, rot!" said Gerald. "Come on! This way to the bun shop."

They went, And it was while Cathy and Jimmy were in the shop
and the others were gazing through the glass at the jam tarts and
Swiss rolls and Victoria sandwiches and Bath buns under the
spread yellow muslin in the window, that Gerald discoursed in
Mabel's ear of the plans and hopes of one entering on a detective
career.

"I shall keep my eyes open tonight, I can tell you," he began. "I
shall keep my eyes skinned, and no jolly error. The invisible
detective may not only find out about the purse and the silver, but
detect some crime that isn't even done yet. And I shall hang about
until I see some suspicious-looking characters leave the town, and
follow them furtively and catch them red-handed, with their hands
full of priceless jewels, and hand them over."

"Oh!" cried Mabel, so sharply and suddenly that Gerald was roused
from his dream to express sympathy.

"Pain?" he said quite kindly. "It's the apples they were rather hard."

"Oh, it's not that," said Mabel very earnestly. "Oh, how awful! I
never thought of that before."

"Never thought of what?" Gerald asked impatiently.

"The window."

"What window?"
