The more La Touche pondered over this theory, the more satisfied he became that he had at last reached the truth. But he had to admit that even yet there were several points he could not understand. When did the murder take place, and where? Did Madame really elope with Felix, and, if so, did her husband bring her back alive or dead? How did the impression of the letter ordering the second statue come to be on Felix’s blotting paper? If Madame was murdered in Paris, how did the jewelled pin reach St. Malo?

But in spite of these and other difficulties, La Touche was more than pleased with his progress, and, as very late he went to his bedroom, he felt a short investigation should be sufficient to test his theory, as well as to clear up all that still remained doubtful.


CHAPTER XXIX

A DRAMATIC DÉNOUEMENT

Three days after the finding of the carter, Dubois, and La Touche’s discovery of what he believed was the true solution of the mystery, he received a letter which interested him considerably. It came by post to his hotel, and was as follows—

‘Rue St. Jean 1,

‘Avenue De L’Alma

‘26th May, 1912.

‘Dear Monsieur,—In connection with your calls here and inquiries into the death of my late mistress, I have just by accident hit on a piece of information which I am sure would be of value to you. It explains the closing of the front door which, you will recollect, I heard about 1.0 a.m. on the night of the dinner party. I think it will have the effect of entirely clearing your client, though I am afraid it does not point to any one else as the murderer. M. Boirac is dining out to-night and most of the servants are attending the marriage festivities of one of the housemaids; the house is therefore unprotected, and I cannot leave it to call on you, but if you could see your way to call here any time during the evening, I shall tell you what I have learnt.
