Punctiliously

"Monsieur Thuran became a frequent visitor at the home of Hazel Strong’s uncle in Cape Town. His attentions were very marked, but they were so punctiliously arranged to meet the girl’s every wish that she came to depend upon him more and more. Did she or her mother or a cousin require an escort—was there a little friendly service to be rendered, the genial and ubiquitous Monsieur Thuran was always available."
