Chapter 1

"Monsieur Tranter! A moment!"

The Right-Honorable John Tranter swung round, latch-key in hand. Behind
him, an enormous figure emerged, with surprisingly agile and noiseless
steps, from the shadow of the adjoining house--a figure almost grotesque
and monstrous in the dim light of the street lamp. The very hugeness of
the apparition was so disconcerting that John Tranter drew back with a
startled exclamation.

"Good Lord! Monsieur Dupont? You in London?"

Monsieur Dupont described circles with his country's largest silk hat.

"I in London! An event, my friend, in the history of your city!"

He laughed softly, and replaced the hat on his head. They shook hands
warmly.

"This is a delightful surprise," Tranter said, turning back to the door.
"Come in."

"It is late," Monsieur Dupont apologized--"but I entreat a moment. It is
three hours only since I arrived, and I have passed one of them on your
doorstep."

"An hour?" Tranter exclaimed. "But surely----"

Monsieur Dupont squeezed himself into the narrow hall with difficulty.

"I possess the gift of patience," he claimed modestly. "In London it is
of great value."

In the small library he looked about him with surprise. The plain,
almost scanty furniture of Tranter's house evidently did not accord with
his expectations of the residence of an English Privy Councillor.
Monsieur Dupont sat down on a well-worn leather couch, and stared,
somewhat blankly, at the rows of dull, monotonous bindings in the simple
mahogany bookcases.

He placed the drink Tranter mixed for him on a small table by his side,
accepted a cigar, and puffed at it serenely. And in that position,
Monsieur Victorien Dupont presented a pleasing picture of elephantine
geniality. He was so large that his presence seemed to fill half the
room. His great face was one tremendous smile. His eyes, though capable
of a disconcertingly direct gaze, were clear and even childlike. His
English was perfect, his evening-dress faultless, and, though obviously
a _bon-viveur_, he was also unmistakably a man with a purpose.

"And what has brought you to London?" Tranter asked, sitting opposite to
him.

"My friend," said Monsieur Dupont, "I am here with a remarkable object.
I have come to use the eyes the good God has given me. And to do so I
beg the assistance of the great position the good God has given you."

"I hope," Tranter returned, "that what you require will enable me to
make some sort of return to the man who saved my life."

Monsieur Dupont waved his hands in a gigantic gesture.

"To restore to the world one of its great men--it was a privilege for
which I, myself, should pay! The service I ask of you is small."

"You have but to name it," said the Privy Councillor.

Suddenly there was no smile on Monsieur Dupont's face. Without the smile
it was a very much less pleasant face.

"Two years ago, in my own country," his voice acquired a new snap, "some
one asked me a riddle."

"A riddle?" Tranter echoed, surprised at the change.

"A very strange riddle. Unfortunately, I cannot tell you what it was. I
cannot tell any one what it was. I undertook to find the answer. From
France the riddle took me far away to another country--and there, after
a year's work, I found half the answer. The other half is in London. And
I am in London to find it."

"This is interesting," said Tranter, smiling slightly at the huge
Frenchman's intense seriousness.

"You, my friend, can help me."

"I am at your service," the other promised.

Monsieur Dupont half-emptied his glass, and the smile began to reappear
on his face in gradual creases. In a moment the shadow had vanished. He
laughed like a jolly giant.

"Ah, forgive me! I had almost committed the crime to be serious. It is a
fault that is easy in your London."

"What do you want me to do for you?" Tranter asked.

"I want," said Monsieur Dupont, "to be taken with you, as your friend
from Paris, to one or two society functions--where I may be likely to
meet ... what I seek."

Tranter was somewhat taken aback.

"Unconsciously," he returned--"though of course, I will make it my
business to fulfill your wishes--you have really asked me a difficult
thing. No man goes less into society than I do. Most people have given
up inviting me."

"Forgive me," said Monsieur Dupont again. "I had imagined I should be
asking a thing the most simple."

"So you are," Tranter assured him. "The fault is with me. Where women
are concerned I am utterly hopeless. I fly from a pretty woman as you
might fly from a crocodile."

"An ugly woman," said Monsieur Dupont, "is the real friend of man--if he
would but know it."

"The dull family dinners of dull family people are the only 'functions'
I ever attend. However, let me see what can be done for you." Tranter
rose, and with an amused expression began to sort out a small pile of
cards on the mantel-piece.

Monsieur Dupont smiled on. He emptied his glass, and inhaled the smoke
of his excellent cigar with all the enjoyment of a satisfied
connoisseur. His glance played from one article of furniture to another,
from the floor to the ceiling, from bookcase to bookcase, from picture
to picture. The very plainness of the room seemed to fascinate him. His
gaze sought out the ugliest picture, and became fixed on it. Tranter
turned over all the cards, and shrugged his shoulders helplessly.

"In a couple of days I shall be able to fix you up a dozen times over,"
he said. "But I am afraid I have scarcely anything to offer you for
to-morrow night. Why didn't you drop me a line in advance?"

"Let us dispense with to-morrow night, then," said Monsieur Dupont.

Tranter ran through the cards again.

"There is a dinner at Lord Crumbleton's--which I have too much regard
for you to suggest. The Countess is a most estimable lady, who has spent
the last fifteen years in vain attempts to become unfaithful to her
husband, and now reads the Apocrypha all day for stimulation. You could
dine with a high-church clergyman who absolves sins, or an actor-manager
who commits them. But stay----" he paused quickly. "I forgot. There is
something else." He sorted out a card. "Here is a possibility of
amusement that had escaped me."

"Ah!" said Monsieur Dupont.

"George Copplestone has favored me with an invitation to a select
gathering at his house at Richmond, which would be very much more likely
to provide answers to riddles. I never accept Copplestone's invitations
on principle--although he goes on sending them. But, if you like, I will
break my rule, and take you. It is sure to be entertaining, if nothing
more."

Monsieur Dupont bowed his gratitude. Tranter replaced the cards, and
returned to his seat.

"Copplestone is a remarkable individual, who has learnt what a multitude
of sins even a slight financial connection with the Theater will cover.
He puts various sums of money into the front of the house to gain
unquestioned admission to the back. He has an extraordinary taste for
fantasy, and is always startling his friends with some new eccentricity.
He is not generally considered to be a desirable acquaintance--and
certainly no man in London has less regard for the conventions."

"To confine myself to desirable acquaintances," said Monsieur Dupont,
"would be my last wish."

"Then we will go to Richmond to-morrow night. He lives in a very strange
house, in a stranger garden--the sort of place that no ordinary normal
person could possibly live in. And I warn you that you will find nothing
ordinary or normal in it. If you are interested in some of the
unaccountable vagaries of human nature, you will enjoy yourself."

"The unaccountable vagaries of human nature," said Monsieur Dupont, "are
the foundation of my riddle."

"Then," Tranter returned, "I could give you no better chance to solve
it. In addition, you will probably make the acquaintance of a certain
pretty society widow, who wants to marry him because of his vices, and
one or two other well-known people who owe him money and can't afford to
refuse to dine with him. Also, as the invitation is an unusually
pressing one, we can rely on the introduction of some unexpected freaks
for our entertainment."

"It is arranged," Monsieur Dupont declared, "I go with you to Richmond."

"Very well," Tranter agreed. "Call for me here at eight o'clock, and we
will go. Help yourself to another drink."

Monsieur Dupont helped himself to another drink.
