You could answer this is a couple of different ways. You could say she got all 100 pounds or you could say she got a little bit more.
Mrs. Wilkinson's claim was for 100 pounds in damages for the mental distress that was inflicted on her by Downton's lie about Mr. Wilkinson. The jury awarded this entire sum to her. In his opinion, Mr. Justice Wright held that the intentional infliction of emotional torment was indeed a tort. He therefore upheld the entire 100 pound claim.
In addition, though, Wright held that Downton was liable for Mrs. Wilkinson's train fare to and from the place where she thought her husband was injured. This amounted to a further 1 shilling 10.5 pence.
Therefore, the entire sum due to Mrs. Wilkinson was 100 pounds, 1s 10.5d.
