Her Eternal Crown: Queen Marie of Romania and the Baha’i Faith, Della L Marcus, pp203
Shoghi Effendi wishes me to write you this short note to inform you that he is not going to send you the bottle of attar of roses as he promised to do in his last letter. The mail is unsafe and they may do this time as they did the last time, for it is almost sure that it is in the post office that the bottle was opened and the attar changed into honey. He will wait until some person is found who is likely to meet you, and will give him the bottle to hand it to you personally. This way there will be no risk incurred.
