Many people wants to know why Holmes could always be aware of those key details.I want to answer this question by Holmes'dictum"Watson,because I am just seeking for it.""Deduction"-first mentioned by Holmes in"A Study in Scarlet".This theory is wildly accepted by all detectives and scientists.For if we want to know how a event is going on,we should first make our hypothesis.Then we can find that something supports our prediction while others do not.So we need to find the more reasonable explanation.Through this procedure,we are gradually approaching the truth.So now you could understand why did Holmes care about the writing style of those letters,why he wanted to know who would be benefit most after the bridegroom disappeared,whyMr.Windibank was only few years older than Miss Sutherland,why Mr Angelcouldn'tspeak very well.
