News of the sudden death of his father, a rubber planter in Malaya, was brought to Brian at the end of his last term at school in England. Suspicious circumstances and a curious silence about the secret formula he knew his father had worked out for an important new process put it into his head to go and see what he could find out for himself. Being inexperienced, he ran straight into the trap laid for him by the man he had most reason to suspect; his father's newly acquired partner. However, he found friends among the Malays and fled to the jungle, from whence the search for the missing formula was carried out. The Plot is thrilling and well sustained, and the picture of life in Malaya good and lively. It is mainly for boys between the ages of 10 and I4 though girls also will enjoy it.
