Mary Louise and the Liberty Girls by L. Frank Baum

The two girls parted at the Liberty Shop. Mary Louise went in "to attend to business," while Josie O'Gorman strolled up the street and paused thoughtfully before the windows of Kasker's Clothing Emporium. At first she didn't notice that it was Kasker's; she looked in the windows at the array of men's wear just so she could think quietly, without attracting attention, for she was undecided as to her next move. But presently, realizing this was Kasker's place, she gave a little laugh and said to herself: "This is the fellow poor little Mary Louise suspected of being the arch traitor. I wonder if he knows anything at all, or if I could pump it out of him if he does? Guess I'll interview old Jake, if only to satisfy myself that he's the harmless fool I take him to be."

With this in mind she walked into the store. A clerk met her; other clerks were attending to a few scattered customers.
