"It is the Donovan Leichmann body that I search for," he said solemnly; "there was a case of sleeping-sickness at the docks, and the Herr Professor of the Tropical School so kindly let me have a little blood for testing."
"Professor," said Beale, sitting down in the place which Parson Homo had vacated and leaning across the table, "are you still working for van Heerden?"
The old man rolled his big head from side to side in an agony of protest.
"Of the learned doctor I do not want to speak," he said, "to me he has been most kind. Consider, Herr Peale, I was starving in this country which hates Germans and regard as a mad old fool and an ugly old devil, and none helped me until the learned doctor discovered me. I am a German, yes. Yet I have no nationality, being absorbed in the larger brotherhood of science. As for me I am indifferent whether the Kaiser or the Socialists live in Potsdam, but I am loyal, Herr Peale, to all who help me. To you, also," he said hastily, "for you have been most kind, and once when in foolishness I went into a room where I ought not to have been you saved me from the police." He shrugged his massive shoulders again. "I am grateful, but must I not also be grateful to the learned doctor?"
"Tell me this, professor," said Beale, "where can I find the learned doctor to-night?"
"At his so-well-known laboratory, where else?" asked the professor.
"Where else?" repeated Beale.
The old man was silent.
"It is forbidden that I should speak," he said; "the Herr Doctor is engaged in a great experiment which will bring him fortune. If I betray his secrets he may be ruined. Such ingratitude, Herr Peale!"
There was a silence, the old professor, obviously distressed and ill at ease, looking anxiously at the younger man.
