He anticipated no difficulty in passing the Customs. None of the officials would detect in the harmless-looking slab that resembled sheet-glue one of the strongest explosives possible to obtain. They were "traveller's samples" and as such were allowed duty free.

So within ten minutes of leaving the West Barbican Ludwig Schoeffer was bowling along in a rickshaw, drawn by a huge, muscular Zulu "boy", en route for a small hotel that overlooked the harbour.

On the following day Schoeffer's explosive, with the detonator timed for its maximum limit, was stored in No. 3 hold of the S.S. West Barbican, as one of the twenty odd cases of hardware consigned by the well-known firm of Van der Veld to Senhor Perez Bombardo of Beira.

Simply but effectively disguised, Schoeffer saw the crate whipped on board and lowered into the hold. So far so good. It looked as if he were certain of success. He chuckled as he conjured up a mental picture of the head director of the Pfieldorf Company handing over a substantial cheque.

During the rest of the West Barbican's stay at Durban, Ludwig Schoeffer lay low. For the present he had done all that was necessary. His deep-laid scheme was progressing favourably.

His idea was to signal the ship by means of wireless and, by spurious authority, order her to Rangoon. It was not unusual for ships of the Blue Crescent Line to receive unexpected orders when on the high seas, since they held roving commissions once they were round the Cape and had landed their mails.

And, since it would take longer than the seven days to make Rangoon, the West Barbican would end her career mysteriously in mid-Indian Ocean.

At ten one morning the West Barbican stood out to sea bound for Beira and Pangawani, at which latter place she was to land the consignment of steelwork for the Kilba Protectorate.

At four the same afternoon Schoeffer walked into the offices of the wireless company at Durban.

"I want this message sent to the West Barbican," he announced, handing in a form written in code—the private code of the Blue Crescent Line.
