Arthur Cadogan West

"The young man who was found dead on the Underground on Tuesday morning.”
"He was twenty-seven years of age, unmarried, and a clerk at Woolwich Arsenal.”

“He has been ten years in the service and has done good work. He has the reputation of being hot-headed and impetuous, but a straight, honest man. We have nothing against him." (Mycroft Holmes)

"Arthur was the most single-minded, chivalrous, patriotic man upon earth. He would have cut his right hand off before he would sell a State secret confided to his keeping." (Miss Violet Westbury)
