“I had learnt that after a murder it is quite proper and conventional for everyone in the house to join the investigators in this entertaining game of hide-and-seek which seemed wholly to absorb us. It was not extraordinary for there to be three total strangers questioning the servants, or for the police to be treated with smiling patronage, or for the corpse to be pulled about by anyone who was curious to know how it had become a corpse. But when I thought of the man to whom the tragedy would be something more than an entrancing problem for talented investigators, I really wondered how these queer customs had arisen.”
