"Very good, I'll see you presently."

Scarcely had the door shut, when Juve pointed to the page. "Look! Doctor Chaleck's signature! And just below it this mark of blood! What do you say to that, sir?"

"But it's sheer madness. Chaleck cannot be guilty!"

"Why not?"

"Because he is known to me. He was recommended to me seven months ago by an old comrade of mine. Chaleck is a man of brains, a foreign physician, a Belgian. He comes here specially to study intermittent fevers. M. Juve, I tell you he has nothing whatever to do with this affair." Juve picked up his hat and stick. He was restless and uneasy; the directors' outburst had not greatly impressed him.

"Doctor Chaleck could not explain how his finger came to be hurt and he did not inform us of the fact."

"A mere coincidence."

"Possibly, but it is a terrible coincidence for that man," replied Juve.

On leaving the director's room, the distinguished detective could not refrain from rubbing his hands. "This time I have him!" he muttered. He went rapidly down the stairs, crossed the great courtyard of the hospital, and proceeded to knock at the porter's lodge.

"Tell me, my friend, precisely how Doctor Chaleck's leaving the hospital came about?"
