Death in the Tunnel is a 1936 detective novel by the British writer Cecil Street, writing under the pen name of Miles Burton.

[1] It is the thirteenth in a series of books featuring the amateur detective Desmond Merrion and Inspector Arnold of Scotland Yard.

Sir Wilfred's behaviour that day had been unusual but not suicidal, his ticket cannot be found anywhere and there were no scheduled railway workers supposed to be the tunnel to stop the train with the light.

A journey on foot through the long and dark tunnel draws their attention to a ventilation shaft halfway down which seems to have played a vital role in the escape of the murderer after he had jumped off the train when it slowed down as well as providing the ghostly light the driver saw.

Their hunt for clues takes them in pursuit of a breakdown truck and a duplicate wallet to Sir Wilfred's, a search that leads them as far afield as Plymouth and Manchester until they are at last able to build up a picture of the elaborate scheme planned by the killers.
