there, still and ever
chatting, loquacious and doleful, lulling their wretchedness to rest
beneath a deluge of tittle-tattle. And when Toussaint, followed by his
son, came out, delighted with the advance he had secured, he also found
them on the same spot. Then he told Madame Theodore the story of the
bradawl, and the idea which had occurred to him and all his mates that
Salvat might well be the culprit. She, however, though turning very pale,
began to protest, concealing both what she knew and what she really
thought.

"I tell you I haven't seen him for several days," said she. "He must
certainly be in Belgium. And as for a bomb, that's humbug. You say
yourself that he's very gentle and wouldn't harm a fly!"

A little later as Pierre journeyed back to Neuilly in a tramcar he fell
into a deep reverie. All the stir and bustle of that working-class
district, the buzzing of the factory, the overflowing activity of that
hive of labour, seemed to have lingered within him. And for the first
time, amidst his worries, he realised the necessity of work. Yes, it was
fatal, but it also gave health and strength. In effort which sustains and
saves, he at last found a solid basis on which all might be reared. Was
this, then, the first gleam of a new faith? But ah! what mockery! Work an

times came round, and casting him into the streets like a dead dog
immediately old age set in.

On reaching Neuilly, Pierre found Bertheroy at Guillaume's bedside. The
old _savant_ had just dressed the injured wrist, and was not yet certain
that no complications would arise. "The fact is," he said to Guillaume,
"you don't keep quiet. I always find you in a state of feverish emotion
which is the worst possible thing for you. You must calm yourself, my
dear fellow, and not allow anything to worry you."

A few minutes later, though, just as he was going away, he said with his
pleasant smile: "Do you know that a newspaper writer came to interview me
about that explosion? Those reporters imagine that scientific men know
everything! I told the one who called on me that it would be very kind of
_him_ to enlighten _me_ as to what powder was employed. And, by the way,
I am giving a lesson on explosives at my laboratory to-morrow. There will
be just a few persons present. You might come as well, Pierre, so as to
give an
