The Clock Struck One by Fergus Hume

With the recovered manuscript in her hands, with the knowledge where it had been found, and with the memory of the clock being wrong, Dora felt convinced that Joad was guilty of the crime. Without doubt he had designed to kill Edermont on that night, and had prepared the alibi so as to prove his innocence should such proof be needed. But what was his motive for the perpetration of so detestable a crime? Why had he stolen the manuscript, and why had he not destroyed so dangerous a piece of evidence? Dora believed that the answer to these questions was to be found in the manuscript itself. The reading of it would probably solve the whole mystery.

Having accomplished her task, she slipped the paper into the pocket of her dress, ran out of the house, and, having locked the door, repaired to the place where she had hidden her bicycle. To give colour to her excuse to Joad, she mounted and rode down the road for some considerable distance. Indeed, she felt inclined there and then to go to Canterbury and assure Allen that he was safe, and that she had won a fortune by discovering the actual criminal; but her desire to do away with any possible suspicions on the part of Joad induced her to abandon such intention. When he found the manuscript gone, he might suspect her if she went directly into Canterbury, whereas, if she behaved as usual, he could have no doubts on the subject.
