Volume V contains the seventh, eighth, and ninth full-length Thorndyke adventures, published in 1924, 1925, and 1926, respectively. With each subsequent narrative, Thorndyke's skills and abilities grown and amaze.

• The Mystery of Angelina Frood - In which a doctor, newly arrived in Rochester, falls in love with Angelina Frood. When she abruptly vanishes, only Thorndyke's skills can discover the truth in a most surprising manner.
• The Shadow of the Wolf - Two men depart on a boat, but only one returns. What follows is one of the best examples of Thorndyke's method as he plays a deadly game with the player on the other side.
• The D'Arblay Mystery - A young doctor discovers a body in a pond. Was it an accident, or suicide, or murder? One thing is certain - the danger has not ended with just one death.
