“Did she carry her attaché-case?”
“Yes. She always does.”
“She did not have it when she went home yesterday morning, for she left it here—the case which your father prepared,” he said. “She brought the second of the cases with her to-night.”
“Then both are here!” exclaimed Ella in excitement.
“Both are now in the power-house. I saw her hand over the second one to Cole only a quarter of an hour ago. Let us watch.”
Then the pair crept on beneath the dark shadows through the rain to the great square building of red-brick which, constructed six months before, contained some of the finest and most up-to-date electrical plant in all the world.
At last they gained the door, which stood slightly ajar. The other mechanics were all away in the canteen having their early morning meal, and the man Cole, outwardly an honest-looking workman, remained there in charge.
Together they watched the man’s movements.
Presently he came to the door, opened it, and looked eagerly out. In the meantime, however, Kennedy and his companion had slipped round the corner, and were therefore out of view. Then, returning within, Cole went to a cupboard, and as they watched from their previous point of vantage they saw him unlock it, displaying the two little leather attaché-cases within.
Close to the huge main dynamo in the centre of the building there stood on the concrete floor six cans of lubricating-oil which, it was proved afterwards, were usually kept at that spot, and therefore were in no way conspicuous.
