Caoimhe felt the frustration growing but was unsure if it was due to the enormity of the task or a lack of confidence in her theory. She had returned to Turlough's place and time so he could visit home, but she had her own motive for coming with him. Ever since she had heard of his brush with a Nocturn she had surmised that the Nocturn had only one real reason for being at this time and place, he was hunting for a book of souls. Evenings of discussions with Annie had allowed her to narrow down the places she needed to visit, after all for the Nocturn to try and take her out, and if it had not been Turlough he would have succeeded, she shivered at the thought, their paths had to of crossed at some point. She doubted the book of souls would be here, it would stand out even in such a massive selection of books, but buried in these books there had to be a clue. The memory of those discussions raised another concern in her mind, Anni was very reluctant to give some information yet she knew only too well how important finding the book before the Nocturn was. She was hiding something but she had no idea what. She decided she would give it another hour and then call it a day. She suspected Turlough would join her soon, not only because he would want to see what she was up to but also because she had 'borrowed' the coffee machine from his house and he would need his caffeine fix.
