Sherlock Holmes and the Time Machine: The Confidential Files of Dr. John H. Watson, Book 4

Sherlock Holmes and his friend, Dr.

John Watson, are no strangers to danger—but a visitor’s claim that they are to be the targets of an assassin is unsettling.

Moreover, the man says he has created a time machine that has whisked him away to the future.

Astonishing! The idea is so outlandish that the great detective considers tossing the man out on the street.

But there’s more.

The assassin will also shoot Queen Victoria’s son, the crown prince, when he steps off a train to celebrate her Diamond Jubilee Celebration.
