For two days he kept his promise to

For two days he kept his promise to the kind young lady. On the morning of the third day, however, he thought of the books he wanted, and he knew he would have to look for another safe. But he never got the chance to begin his plan. By noon a policeman had arrested him for the jewel robbery at Shotover Grange.
His fingerprints, for he had opened the safe without gloves, were all over the room, and no one believed his story of the wife of the owner of the house asking him to open the safe for her, The wife herself, a gray-haired, sharp-tongued woman of sixty, said that the story was nonsense.
Horace is now the assistant librarian in the prison. He often thinks of that charming, clever young lady who was in the same profession as he was, and who tricked him. He gets very angry when anyone talks about “honor among thieves.”
