Sherlock Holmes get out of town because Grant Colwyn is here to stay! In The Shrieking Pit the reader is introduced to the renowned American detective Grant Colwyn. The story begins when this internationally famous detective is dining in a hotel restaurant and is made aware of the strange behavior of a fellow guest. This strange behavior is brought to his attention by another guest, Sir Henry Durwood (a well known doctor and amateur paleontologist). His diagnosis is that the young man is suffering from a rare form of epilepsy and may soon present a danger to other hotel guests. The two men restrain the man and take him to his room. The following day the young man left the hotel early before anyone was up. The next day, in another neighboring town a murder is committed and this same man is the main (only) suspect. Although all the circumstantial evidence points to him as the murderer, Grant Colwyn believes in his innocence and sets out to prove it. Grant Colwyn goes about his work in a clear and precise manner without making the reader feel inferior with his “obvious deductions” and he is warmer and infinitely more likeable that the famous Sherlock Holmes.
