What are some adjectives that describe Sir Charles?

Shrewd, nervous..... practical

“This family paper was committed to my care by Sir Charles Baskerville, whose sudden and tragic death some three months
ago created so much excitement in Devonshire. I may say that I was his personal friend as well as his medical attendant. He was a strong-minded man, sir, shrewd, practical, and as unimaginative as I am myself. Yet he took this document very seriously, and his mind was prepared for just such an end as did eventually overtake him.”
