THE BURGLARY AT THE VICARAGE (CHAPTER 5)

The burglary at the vicarage occurred in the small hours of Whit-Monday

Mrs. Bunting woke up on hearing the door of their bedroom opening & then closed.

When she was sure of the presence of someone she aroused her husband the Rev. Mr. Bunting.

Without striking a light, he put on his spectacles, dressed himself and her went out on the landing to listen.

On hearing a fumbling going on at his study desk down-stairs, and a violent sneeze, he returned to his bedroom, armed himself a poker, and descended the staircase as noiselessly as possible.

Then they heard sounds of something snapping, drawer opening and rustle of paper.

Then a match was struck and the study was flooded with yellow light.

Mr. Bunting who was now in the hall, could see the desk and the open drawer and a candle burning on the desk.

The chink of money, the housekeeping reserve of gold, -- two pounds ten in half sovereigns altogether, put Mr. Bunting in action and gripping the poker firmly, he rushed into the room and shouted at the burglar to surrender.

But to his amazement the room was perfectly empty yet they felt somebodys presence in the room.

Mr. &Mrs. Bunting went across the room and looked behind the screen, under the desk, behind the window-curtains, even up the chimney, in waste-paper basket and the coal-scuttle.

Then they heard a violent sneeze in the passage. And as they rushed out, they saw the kitchen door slammed and heard a sound of bolts being hastily shot back.

Through the scullery, they saw the back door opening and then closed with a slam.

They refastened the back door, examined the kitchen, pantry, and scullery thoroughly, but there was not a soul to be found in the house.
