In the final part of our exclusive Sherlock Holmes adventure, the celebrated detective deduces the link between the delivery of seven macabre Christmas cards, a burglary and a violent murder but in doing so puts his own life in danger.
The next morning found Holmes staring moodily out of the window. Although the first and second post had already been delivered, no further cards had arrived and it seemed that there was little we could do but wait. Now there is a sad story, Holmes remarked. A young man marries above himself. In order to support his wife, he takes himself to the colonies and there accumulates a certain amount of wealth.
