Inspector Frost is called in when a body is found stabbed in Bolter’s Court in the City of London. The young man found bending over the corpse would seem the obvious suspect – and the revelation that the man is none other than the famous American millionaire Mckinley M. Macmillan causes a sensation in the press. But the fact that the victim was not shot, but stabbed with an antique dagger is just one of several details that leads Frost to suspect that all may not be as it seems…

Originally published in 1930, this vintage murder mystery is the third novel to feature Inspector Frost.
