"Bishop's Crossing is a small village lying ten miles in a south-westerly direction from Liverpool. Here in the early seventies there settled a doctor named Aloysius Lana. Nothing was known locally either of his antecedents or of the reasons which had prompted him to come to this Lancashire hamlet. Two facts only were certain about him; the one that he had gained his medical qualification with some distinction at Glasgow; the other that he came undoubtedly of a tropical race, and was so dark that he might almost have had a strain of the Indian in his composition. His predominant features were, however, European, and he possessed a stately courtesy and carriage which suggested a Spanish extraction."]]>
